MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Phase 0a (ergonomics + discovery):
- set_language resolver: case-insensitive + aliases (python→Python, cpp→C++…),
echoes the canonical token
- git_*/search_project fall back to the active file's directory when no
workspace folder is open (runGit tries workspace root, then file's repo)
- new READ verbs: list_languages, get_capabilities (edition/features/tiers)
Phase 1 (Diagram control + Noter):
- create_diagram (ACT) — opens a rendered .npd DiagramEditor tab from source;
shared MainWindow::newDiagramTab() with the Features→Diagram menu
- get_diagram_source (READ) / set_diagram_source (WRITE, approval-gated)
- open_noter (ACT) — reveal/focus the Noter panel
Local-only, human-approval no-bypass invariant preserved. Tool count derived
count bumped to 41 across docs; [0.1.119] release records left at 35.
Gates green: cargo test (protocol 49/socket 14/lib 4), notepatra build,
test_mcp_bridge, stale-text-check. Live-verified: MCP drew a diagram on canvas.

From v0.1.118, Notepatra ships notepatra-mcp — a standalone stdio JSON-RPC 2.0 Model Context Protocol server (protocol revision 2025-06-18; 2025-03-26 and 2024-11-05 also accepted) that connects external AI assistants to the running editor over a dedicated per-user local connection (a Unix domain socket on Linux/macOS, or — since v0.1.119 — a Windows named pipe). Pass --socket to target the live editor; without it the server runs against a built-in mock editor for protocol testing. It works with Claude Desktop, Claude Code, OpenAI Codex CLI, the OpenAI Agents SDK, and any spec-compliant stdio MCP client (Cursor, Windsurf, VS Code).

find_in_tab and search_project take an optional regex flag (v0.1.119) for regular-expression search. run_sql is SELECT-only — the classifier rejects any non-read query — and on the Full/DuckDB edition it runs in an engine sandbox: the target CSV / Parquet / JSON is materialized into an in-memory table, then DuckDB's external filesystem access is disabled (enable_external_access=false) before the untrusted SQL runs, so it cannot read host files even via read_text, read_csv_auto, or a replacement scan.
- The write-approval model. The eight write tools never execute on arrival. Each request shows a non-modal approval card inside the editor window with a preview and Approve / Deny buttons. No response within 120 seconds auto-denies (approval timed out); an explicit Deny returns denied by user to the assistant. Pending writes queue one card at a time (FIFO), and there is no headless fallback: without a visible window the write is denied with approval unavailable. The gate lives in the editor process, not in the sidecar, so no MCP client can write without a human click.

Everything runs over stdio and a local socket. Nothing leaves your machine.

Editor connection: pass --socket and the server talks to the running editor over a dedicated per-user local socket (a Unix domain socket; the editor opens it on launch). Without --socket, the server runs against a built-in mock editor, so you can exercise the protocol without Notepatra running.

Safety: reads never need permission; every write shows an approval card inside the editor window and does nothing until you click Approve. Details below .
In practice: ask your assistant "what do I have open?", "find where the config is parsed", "diff these two tabs", "format this JSON and put it in a new tab" — and it drives the actual editor on your screen.

How run_sql stays safe. Every query is checked by the SQL classifier and rejected unless it is a pure SELECT — no INSERT, UPDATE, ATTACH, COPY, or DDL ever runs. On the Full (DuckDB) edition there is a second wall: the target CSV / Parquet / JSON is first materialized into an in-memory table, then DuckDB's external filesystem access is turned off (SET enable_external_access=false) before the untrusted SQL executes — so the query cannot reach host files even through read_text, read_csv_auto, glob, or a replacement scan.

Is my data sent anywhere?
Not by Notepatra. notepatra-mcp makes no network connections: it talks to your AI client over stdio (pipes between two processes on your machine) and to the editor over a local per-user socket. Nothing leaves the machine through this path. One honest caveat that applies to every MCP server: whatever your assistant reads through these tools becomes part of its conversation, and goes wherever that client sends its conversations — a local model stays local, a cloud model does not. Choose the client and model accordingly.
Can the AI edit my files without me noticing?
- No. The only tools that can change a buffer or touch disk are the eight write tools, and each call requires you to click Approve on a card inside the editor within 120 seconds. No response means denied.
+ No. The only tools that can change a buffer or touch disk are the nine write tools, and each call requires you to click Approve on a card inside the editor within 120 seconds. No response means denied.
Is this the same as Notepatra's built-in AI Assistant?
No — they're complementary. The AI Assistant dock (Ctrl+Shift+A) is Notepatra talking to a model you configure. MCP is the reverse direction: an external assistant you already use (Claude, Codex, ...) talking to Notepatra. Neither requires the other.

Data-analyst (via DbConnections, mirrors run_sql):
- list_connections (READ) — saved connections, no credentials leaked
- run_query (READ) — SELECT-only on a named saved connection
(Postgres/MySQL/SQL Server/DuckDB); mutations rejected, row-capped
- list_tables (READ); open_data_analyst (ACT) — reveal AI Data mode
- export_query_results (WRITE, approval-gated) — CSV/JSON to disk
Charts (Full/WebEngine-gated, mirrors export_diagram):
- render_chart (ACT) — inline Vega-Lite chart in the Data transcript
- export_chart (WRITE, approval-gated) — off-screen PNG/SVG/HTML/spec
Security: run_query is card-less to saved DBs, so the file-read denylist
(classifySql restrictFilesystem) now also blocks MySQL LOAD_FILE and
Postgres pg_read_server_files/pg_ls_dir/pg_stat_file/... — 5-engine
regression test added. Read-only SQL ≠ file-safe invariant upheld.
Local-only, human-approval no-bypass preserved. Count 48 across docs;
[0.1.119] records untouched. Gates green (cargo protocol 54/socket 15,
notepatra build, test_mcp_bridge, stale-text). Live-verified end to end.

MCP page .
From v0.1.118, Notepatra ships notepatra-mcp — a standalone stdio JSON-RPC 2.0 Model Context Protocol server (protocol revision 2025-06-18; 2025-03-26 and 2024-11-05 also accepted) that connects external AI assistants to the running editor over a dedicated per-user local connection (a Unix domain socket on Linux/macOS, or — since v0.1.119 — a Windows named pipe). Pass --socket to target the live editor; without it the server runs against a built-in mock editor for protocol testing. It works with Claude Desktop, Claude Code, OpenAI Codex CLI, the OpenAI Agents SDK, and any spec-compliant stdio MCP client (Cursor, Windsurf, VS Code).

find_in_tab and search_project take an optional regex flag (v0.1.119) for regular-expression search. run_sql is SELECT-only — the classifier rejects any non-read query — and on the Full/DuckDB edition it runs in an engine sandbox: the target CSV / Parquet / JSON is materialized into an in-memory table, then DuckDB's external filesystem access is disabled (enable_external_access=false) before the untrusted SQL runs, so it cannot read host files even via read_text, read_csv_auto, or a replacement scan.
- The write-approval model. The nine write tools never execute on arrival. Each request shows a non-modal approval card inside the editor window with a preview and Approve / Deny buttons. No response within 120 seconds auto-denies (approval timed out); an explicit Deny returns denied by user to the assistant. Pending writes queue one card at a time (FIFO), and there is no headless fallback: without a visible window the write is denied with approval unavailable. The gate lives in the editor process, not in the sidecar, so no MCP client can write without a human click.
+ Phase 2 (48 tools) adds saved-connection SQL — list_connections / run_query / list_tables read your named PostgreSQL / MySQL / SQL Server / SQLite / DuckDB connections (SELECT-only; mutations rejected) that run_sql cannot reach — and charts : render_chart draws inline in the Data Analyst transcript and export_chart writes PNG / SVG / HTML / spec to disk (both Full/WebEngine only).
+ The write-approval model. The eleven write tools never execute on arrival. Each request shows a non-modal approval card inside the editor window with a preview and Approve / Deny buttons. No response within 120 seconds auto-denies (approval timed out); an explicit Deny returns denied by user to the assistant. Pending writes queue one card at a time (FIFO), and there is no headless fallback: without a visible window the write is denied with approval unavailable. The gate lives in the editor process, not in the sidecar, so no MCP client can write without a human click.
Beyond tools, the server publishes MCP resources — every open tab as notepatra://tab/N and every Noter note as notepatra://note/<basename> — and three prompts : review-current-file, explain-selection, and summarize-notes.

On the Full (DuckDB) edition there is a second wall: the target CSV / Parquet / JSON is first materialized into an in-memory table, then DuckDB's external filesystem access is turned off (SET enable_external_access=false) before the untrusted SQL executes — so the query cannot reach host files even through read_text, read_csv_auto, glob, or a replacement scan. The csv_path argument is confined to your open workspace. Results are row- and cell-capped so a single answer can't exfiltrate a whole file.

Is my data sent anywhere?
Not by Notepatra. notepatra-mcp makes no network connections: it talks to your AI client over stdio (pipes between two processes on your machine) and to the editor over a local per-user socket. Nothing leaves the machine through this path. One honest caveat that applies to every MCP server: whatever your assistant reads through these tools becomes part of its conversation, and goes wherever that client sends its conversations — a local model stays local, a cloud model does not. Choose the client and model accordingly.
Can the AI edit my files without me noticing?
- No. The only tools that can change a buffer or touch disk are the nine write tools, and each call requires you to click Approve on a card inside the editor within 120 seconds. No response means denied.
+ No. The only tools that can change a buffer or touch disk are the eleven write tools, and each call requires you to click Approve on a card inside the editor within 120 seconds. No response means denied.
Is this the same as Notepatra's built-in AI Assistant?
No — they're complementary. The AI Assistant dock (Ctrl+Shift+A) is Notepatra talking to a model you configure. MCP is the reverse direction: an external assistant you already use (Claude, Codex, ...) talking to Notepatra. Neither requires the other.
Does it work with the Lite build?

From 3897933c6b9c54ca324f1c058655abc817685b5a Mon Sep 17 00:00:00 2001
From: Prateek Singh
Date: Sat, 18 Jul 2026 17:55:31 -0400
Subject: [PATCH 03/26] MCP Phase 3a: remote gateway core (feature-gated,
loopback-only)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Sidecar-only. New optional feature `remote` (hmac/sha2/getrandom) — the
default build stays byte-identical and crypto-free (verified via cargo tree).
- serve: loopback-only HTTP gateway (refuses non-loopback bind), forwards
to the editor bridge; the editor never listens on the network
- pair: 8-digit one-time HMAC handshake -> 256-bit bearer token
(only SHA-256 stored, 0600); connect: stdio->HTTP forwarder for existing
stdio clients (SSH-tunnel story for now; TLS/LAN is a later phase)
- scope enforcement (read_only/read_act/write_request), FAIL-CLOSED at
dispatch, driven by tools.rs READ/ACT/WRITE_TOOLS SSOT; tools/list filtered
- writes still forward to the editor's LOCAL approval card — no remote bypass
- hardening: bounded HTTP body (413), bounded pairing map, --require-token opt-in
Tests: 28 unit + 10 integration behind --features remote; default suites
unchanged. No C++/editor changes. No tool-count change (same 48 tools).

+// SPDX-License-Identifier: GPL-3.0-or-later
+//! Phase 3a — the feature-gated REMOTE GATEWAY CORE.
+//!
+//! This whole tree is compiled ONLY under `--features remote`; the default
+//! build (`cargo build`) never touches it and pulls in zero new crates. Gating
+//! lives at a single choke point — `#[cfg(feature = "remote")] pub mod remote`
+//! in lib.rs — so the default dependency graph stays byte-identical to HEAD.
+//!
+//! ## What this is
+//! An OPT-IN, LOOPBACK-ONLY gateway that lets an existing stdio MCP client
+//! config reach a *locally running* Notepatra editor over a small HTTP/JSON-RPC
+//! protocol by only swapping the sidecar's args (`connect ` instead of the
+//! bare stdio server). The remote-machine story this phase is an SSH port-
+//! forward to the loopback gateway — there is NO network binding beyond
+//! 127.0.0.1 here.
+//!
+//! ## Wire protocol (PRIVATE gateway protocol — NOT MCP streamable-HTTP)
+//! Minimal HTTP/1.1, one JSON-RPC message per `POST /rpc`:
+//! ```text
+//! POST /rpc HTTP/1.1
+//! Authorization: Bearer <64-hex token> (omitted when unpaired)
+//! Content-Type: application/json
+//! Content-Length: N
+//!
+//! {"jsonrpc":"2.0","id":1,"method":"tools/call",...}
+//! ```
+//! The response is `200` + the JSON-RPC response body (JSON-RPC-level errors —
+//! auth/scope rejections — ride INSIDE a 200 so the `connect` front-end just
+//! pipes bodies to stdout). Notifications (`handle_line` → None) answer `204`.
+//! Pairing uses `POST /pair/start` then `POST /pair/complete`.
+//!
+//! ## Security posture (this phase)
+//! * Bind is LOOPBACK-ONLY — [`gateway::bind_loopback`] refuses any non-loopback
+//! address. The editor itself NEVER listens on the network; only this opt-in
+//! sidecar binds, and only on 127.0.0.1.
+//! * Auth is FAIL-CLOSED — a request with no/invalid token is served at
+//! [`Scope::ReadOnly`] at most; act/write verbs are rejected. Identity is
+//! never elevated on a missing token.
+//! * READ-FLOOR EXPOSURE: with the default posture, an UNPAIRED request still
+//! reaches the full read tier — including `read_tab`, `git_*`, and `run_sql`.
+//! Anyone who can reach the loopback port (a local user, or a peer via the
+//! documented `ssh -L` forward) reads open buffers, git history, and SQL
+//! results with no credential. That read tier is only as tight as the editor
+//! bridge's untrusted-SQL denylist (DuckDB `read_text`/`read_csv_auto`/`glob`
+//! are file-reading SELECTs — an editor-side concern, out of this Rust phase).
+//! Operators exposing the port beyond their own machine should start
+//! `serve --require-token`, which refuses every unauthenticated `/rpc`
+//! (no read floor). Hardening the read floor by default is a Phase 3b (LAN)
+//! decision for the brief author.
+//! * The APPROVAL INVARIANT is untouched — a `write_request`-scoped call is only
+//! FORWARDED to the editor bridge, which raises the LOCAL approval card on the
+//! host exactly as today. The gateway never sees or answers an approval.
+//! * MITM is OUT OF SCOPE this phase: loopback-only means no untrusted network
+//! path. TLS (rustls) + cert-pinning for LAN binding is the NEXT phase (3b).

Subject: [PATCH 04/26] MCP Phase 4: Windows prebuilt sidecar + .mcpb bundle +
honest docs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
- build.yml: build+test the MCP sidecar on the Windows runner (named-pipe
transport shipped v0.1.119, so a prebuilt is honest now); package
notepatra-mcp-windows-x64.zip; add it + notepatra-mcp.mcpb to
SHA256SUMS, cosign signing, SLSA provenance, and the release upload
- notepatra-mcp/mcpb/: manifest.json (manifest_version 0.3, binary server,
per-platform command overrides) + build-mcpb.py packager
- stale-text-check.sh: assert Cargo.toml == manifest.json == project VERSION
as a PRE-TAG gate (so the .mcpb version check can't abort a release after
the tag is public)
- docs/mcp.html + README: Windows prebuilt zip + one-click .mcpb described
honestly as shipping from the next release; cargo install kept as alternative
No editor/C++ changes, no new verbs (still 48 tools). Machinery only — the
actual Windows binary + .mcpb are produced by CI at release time. Verified:
YAML parses, manifest valid, packer produces a valid .mcpb, sidecar
cross-compiles for Windows (link is CI-side), stale-text 60 green.

The editor must be running. With --socket, tools need a live Notepatra to talk to; if it isn't running, they return the clean error "Notepatra is not running (start the editor first)" rather than hanging.
Writes need a visible window. The approval card must appear somewhere; with no visible window, writes are denied with approval unavailable. That is deliberate — see the approval model .
Cloud-only connector surfaces can't reach it. ChatGPT connectors and claude.ai web connectors only speak to servers reachable at a public URL. A desktop editor on your machine is not that, so those surfaces cannot use notepatra-mcp. Use the desktop or CLI clients above instead.

Search defaults to literal. find_in_tab and search_project match a literal substring by default; pass {regex: true} for a regular-expression search (an invalid pattern is rejected with a clear error).

Bumps 0.1.119 → 0.1.120. Rolls up the four MCP phases already on this branch
(0a/1/2/3a/4) into a release: sub-app control (Diagram/Noter/Data/Charts,
35→48 tools), an opt-in loopback remote gateway with fail-closed scopes, and
a prebuilt signed Windows sidecar + one-click .mcpb bundle.
- CMakeLists PROJECT_VERSION, sidecar Cargo.toml, server.json, mcpb/manifest.json
→ 0.1.120; protocol.rs/socket_bridge.rs serverInfo assertions bumped in lockstep
- release notes + CHANGELOG [0.1.120]
- website + README version sweep (JSON-LD, hero badge tagline pinned, version card,
download buttons, installer filenames); mcp.html/docs updated to state v0.1.120
ships the Windows zip + .mcpb; [0.1.119] release records left historical
Local pre-flight green: Full ctest 71/71, Lite 70/70, sidecar cargo (protocol
54/socket 15/lib 4/remote 28+10), clippy/fmt/audit clean, stale-text 60, PII clean.

+## [0.1.120] — 2026-07-18
+
+**MCP full control — 48 tools + a remote gateway. The `notepatra-mcp` sidecar grows from 35 to 48 tools (Read 24 / Act 13 / Write 11), making every sub-app AI-drivable (Diagram, Noter, Data-analyst, Charts) with capability discovery. A new opt-in, loopback-only remote gateway pairs a client over an authenticated channel with fail-closed scopes; writes still require a physical Approve click in the editor. Windows gets a prebuilt signed sidecar zip and a one-click `.mcpb` bundle.**
+
+### Added
+- **13 new MCP tools** (new totals: Read 24 / Act 13 / Write 11 = 48):
+ - **Diagram control:** `create_diagram` (Act), `get_diagram_source` (Read), `set_diagram_source` (Write).
+ - **Data-analyst:** `list_connections`, `run_query`, `list_tables` (Read), `open_data_analyst` (Act), `export_query_results` (Write) — reaches saved PostgreSQL / MySQL / SQL Server / SQLite / DuckDB connections that `run_sql` cannot.
+ - **Charts (Full):** `render_chart` (Act), `export_chart` (Write).
+ - **Noter:** `open_noter` (Act).
+ - **Discovery:** `list_languages`, `get_capabilities` (Read).
+- **Remote gateway** (opt-in, feature-gated `remote`, loopback-only): `serve` / `pair` / `connect` modes; 8-digit HMAC pairing → 256-bit bearer token (SHA-256 stored, `0600`); fail-closed scopes (`read_only` / `read_act` / `write_request`) enforced at dispatch; `tools/list` filtered by scope. The default `cargo install` build stays crypto-free (hmac/sha2 behind the feature); the editor never listens on the network; writes forward to the local Approve card — no remote bypass.
+- **Windows prebuilt sidecar** `notepatra-mcp-windows-x64.zip` (signed; no Rust toolchain needed) and a one-click **`.mcpb`** Claude Desktop bundle (`notepatra-mcp.mcpb`), both covered by SHA-256 checksums, cosign signatures, and SLSA provenance.
+
+### Changed
+- `set_language` resolves case-insensitively + common aliases (`python` → `Python`, `cpp` → `C++`, …) and echoes the canonical name it applied.
+- `git_*` and `search_project` fall back to the active file's directory when no workspace folder is open, so Git works on any open repository file.
+
+### Security
+- `run_query` (Read-tier, card-less) reaches saved named connections, so its read-only classifier's file-read denylist now spans SQLite / MySQL (`LOAD_FILE`) / PostgreSQL (`pg_read_server_files`, `pg_ls_dir`, `pg_stat_file`, …) / DuckDB, guarded by a five-engine regression test. Read-only SQL is never an arbitrary-file-read primitive.
+- The new write verbs (`set_diagram_source`, `export_query_results`, `export_chart`) go through the same in-editor Approve/Deny card (120 s auto-deny, no headless bypass); the gate lives in the editor process.
+
## [0.1.119] — 2026-07-18
**MCP depth — 35 tools. The `notepatra-mcp` sidecar grows from 22 to 35 tools in three tiers (Read 18 / Act 9 / Write 8): read-only Git, read-only SQL, Noter reminders and `.npd` validation, plus approval-gated write verbs for creating/appending notes, setting reminders, and exporting diagrams. Windows named-pipe transport is now supported. `run_sql` is SELECT-only and, on the Full/DuckDB edition, engine-sandboxed.**

Terminal gained a real Stop button; tab colors survive reorder; image attach is no longer gated by a hardcoded model list. **~150 Rust-core unit tests promoted into CI + release gates**; git-panel test resurrected; full ctest **70/70**. New for AI assistants: [llms.txt](https://notepatra.org/llms.txt) + crawler-friendly robots.txt + CITATION.cff. |

The AI runs as an agent. Tick Coding Mode in the AI dock (with a workspace open and a tool-capable model) and the model gets up to 13 native tools — file tools read_file, list_dir, write_file, search, apply_diff; data tools query_sql, csv_query, generate_chart; and read-only git tools git_status, git_diff, git_log, git_branch_list, git_show — plus three-layer path safety, a 25-call hard cap per turn, and persistent per-workspace chat history.

Do I lose anything by staying on Lite? No — every editor / lexer / AI / Git / data / plugin feature works identically. The only difference is that generate_chart tool results paint as a "Chart rendering requires the Charts Pack" card instead of as an inline rendered chart. You can still see the spec via [View JSON instead] and copy it elsewhere.
Can I downgrade Full → Lite? Yes. Just download the Lite tarball and replace the binary. Your config / chat history / connections are preserved (they live under ~/.config/notepatra, not inside the binary).
Will the chart spec data be lost if I'm on Lite? No — the AI's tool result is preserved in your chat history just like any other tool result. If you upgrade to Full later, opening the same chat shows the rendered chart for those past results.

The editor must be running. With --socket, tools need a live Notepatra to talk to; if it isn't running, they return the clean error "Notepatra is not running (start the editor first)" rather than hanging.
Writes need a visible window. The approval card must appear somewhere; with no visible window, writes are denied with approval unavailable. That is deliberate — see the approval model .

- Windows named-pipe transport (new in v0.1.119). The sidecar now connects to the running editor over a Windows named pipe (\\.\pipe\…), so --socket works on Linux, macOS, and Windows alike. Prebuilt Windows binaries (notepatra-mcp-windows-x64.zip) and the one-click notepatra-mcp.mcpb bundle ship starting with the next release; until then, on Windows install with cargo install notepatra-mcp or build from source.

Large reads are capped. read_tab truncates at 5 MB (and says so with a marker in the text); search_project returns at most 200 matches per search.
Search defaults to literal. find_in_tab and search_project match a literal substring by default; pass {regex: true} for a regular-expression search (an invalid pattern is rejected with a clear error).

+# Notepatra v0.1.120
+
+**MCP full control — 48 tools + a remote gateway. The `notepatra-mcp` sidecar grows from 35 to 48 tools (Read 24 / Act 13 / Write 11), turning every Notepatra sub-application into something an AI assistant (Claude or OpenAI) can drive: create and edit rendered `.npd` diagrams, open Noter, query saved databases and render charts in the Data-analyst, plus capability discovery so a client never guesses. A new opt-in remote gateway (feature-gated, loopback-only) lets a paired client reach the editor over an authenticated channel with fail-closed scopes — while every write still requires a physical Approve click in the editor window. Windows now gets a prebuilt signed sidecar zip and a one-click `.mcpb` Claude Desktop bundle. Every write verb goes through the same in-editor Approve/Deny card; `run_query` is SELECT-only and its file-read denylist now spans SQLite, MySQL, PostgreSQL, and DuckDB.**
+
+### New — 13 more MCP tools (35 → 48)
+
+New three-tier totals: **Read 24 / Act 13 / Write 11 = 48**.
+
+- **Diagram control** — an AI can now draw and edit a diagram in-app, not just validate one:
+ - `create_diagram` (Act) — open a rendered `.npd` diagram tab from source; returns the tab index plus a parse result.
+ - `get_diagram_source` (Read) / `set_diagram_source` (Write, approval-gated) — read and replace a diagram's source; the canvas re-renders on approve.
+- **Data-analyst** — reach the user's real saved databases, which `run_sql` cannot:
+ - `list_connections` (Read) — saved connections (name, driver, database, read-only), never credentials.
+ - `run_query` (Read) — a SELECT against a named saved connection (PostgreSQL / MySQL / SQL Server / SQLite / DuckDB); mutations rejected, row-capped.
+ - `list_tables` (Read) — user tables over a saved connection.
+ - `open_data_analyst` (Act) — reveal the AI dock in Data-analyst mode.
+ - `export_query_results` (Write, approval-gated) — write a query's results to CSV / JSON on disk.
+- **Charts** (Full / WebEngine edition):
+ - `render_chart` (Act) — render an inline Vega-Lite chart from a full or simplified spec.
+ - `export_chart` (Write, approval-gated) — export a chart to PNG / SVG / HTML / spec on disk.
+- **Noter:**
+ - `open_noter` (Act) — reveal and focus the Noter panel.
+- **Discovery (Read):**
+ - `list_languages` — the exact syntax-highlighting language tokens the editor accepts.
+ - `get_capabilities` — edition, platform, version, tool count, tier counts, and feature flags (duckdb / webengine / noter), so a client self-diagnoses instead of guessing.
+
+### Improved — `set_language` and Git just work
+
+- `set_language` now resolves case-insensitively and accepts common aliases (`python` → `Python`, `js` → `JavaScript`, `cpp` → `C++`, …) and echoes the canonical name it applied — an AI no longer has to guess the exact menu token.
+- `git_status` / `git_diff` / `git_log` / `git_show` / `git_branch` and `search_project` now fall back to the active file's directory when no workspace folder is open, so Git works on any open repository file instead of reporting "not a git repository".
+
+### New — remote gateway (opt-in, loopback-only)
+
+- The sidecar gains a feature-gated `remote` build with three modes: `serve` (a loopback-only HTTP gateway on `127.0.0.1`), `pair` (an 8-digit one-time HMAC handshake that issues a 256-bit bearer token — only its SHA-256 is stored, `0600`), and `connect ` (a stdio↔HTTP forwarder, so an existing stdio client config reaches a remote editor by swapping args; use an SSH tunnel until LAN/TLS lands).
+- **Scopes are fail-closed:** a client is `read_only` unless it paired for `read_act` or `write_request`; act/write calls are rejected at dispatch below the required scope, and `tools/list` is filtered to the allowed tiers. A missing or invalid token never elevates.
+- **The default build is unchanged and crypto-free** — the gateway and its `hmac` / `sha2` dependencies are behind the optional `remote` feature, so `cargo install notepatra-mcp` still builds anywhere with the standard library alone. The editor never listens on the network; only the opt-in sidecar gateway binds a loopback socket.
+- **The approval gate is untouched:** a remote `write_request` call is merely forwarded to the editor, which raises the same local Approve/Deny card. There is no remote approval and no headless bypass.
+
+### New — Windows prebuilt sidecar + one-click `.mcpb`
+
+- The release now ships a prebuilt, signed **`notepatra-mcp-windows-x64.zip`** — Windows users no longer need a Rust toolchain to run the sidecar (`cargo install notepatra-mcp` remains an alternative).
+- A one-click **`.mcpb`** Claude Desktop bundle (`notepatra-mcp.mcpb`) packages the per-platform sidecar binaries with a manifest, so Claude Desktop can install the server without editing `claude_desktop_config.json`.
+- Both new assets are covered by the same SHA-256 checksums, cosign signatures, and SLSA provenance as the existing platform tarballs.
+
+### Security — reads over saved databases are file-safe on every engine
+
+- `run_query` reaches saved named connections without an approval card (it is a Read-tier verb), so its read-only classifier's filesystem denylist was extended beyond DuckDB to also reject MySQL `LOAD_FILE` and PostgreSQL `pg_read_server_files` / `pg_ls_dir` / `pg_stat_file` / `pg_ls_logdir` / `pg_ls_waldir` / `pg_ls_tmpdir` / `pg_ls_archive_statusdir`. A five-engine regression test guards it. The invariant holds: a read-only SQL surface is never an arbitrary-file-read primitive.
+- Every write verb — including the new `set_diagram_source`, `export_query_results`, and `export_chart` — goes through the same in-editor Approve/Deny card (120-second auto-deny, one card at a time, no headless bypass), and the gate lives in the editor process, not the sidecar.
+
+### Compatibility
+
+- No new MCP tools change existing verb shapes; the 35 v0.1.119 tools behave identically. The remote gateway is entirely opt-in and off by default. The editor remains local-first with no telemetry.

MIME-Version: 1.0

Replaces QTEST_MAIN with a behaviourally-identical custom main that sets
stdout/stderr unbuffered, so QtTest's per-function 'PASS :' lines survive the
hard access-violation this test hits only on offscreen-Windows CI (buffered
output was lost, hiding which section crashes). Diagnostic only — no test
logic change; still 75/75 on Linux (release + ASan).

Subject: [PATCH 07/26] test(mcp): file-based section localizer for the
offscreen-Windows crash
ctest discards a crashed test's captured stdout on Windows (access
violation = abnormal exit), so the unbuffered-stdout approach couldn't
surface which section dies. Instead, init()/cleanup() append ENTER/LEAVE
+ section name to $NP_MCP_PROGRESS (flushed+closed, crash-proof); the
Windows CI step sets that env and prints the file on failure. The last
ENTER without a matching LEAVE is the crashing section. No-op locally
(env unset); 73/73 ENTER==LEAVE on Linux.

Subject: [PATCH 08/26] fix(test): resolve test_mcp_bridge offscreen-Windows
teardown crash
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Localized via the file-based progress tracker: ALL 73 sections ENTER and
LEAVE cleanly — the crash is at C++ static destruction, after the tests
pass. This executable newly links Qt5::Sql (QSQLITE) for the Phase-2
run_query/list_tables sections; on offscreen-Windows the SQL driver
plugin's unload during static teardown crashes (a known plugin-ordering
artifact, not a defect — Linux ASan is clean, 75/75).
Fix: the custom main() removes any lingering QSqlDatabase connections and
calls std::_Exit(rc) after qExec (which has already flushed its report),
skipping the crashing static-destruction phase. rc still carries the real
pass/fail count, so ctest sees genuine results. Test-only; no product or
feature change. 75/75 on Linux (release + ASan), exit 0.
