What does this PR do?

There are two ways to get altimate-code's data tools into another agent today, and both are poor fits:

• The Claude Code plugin hands the whole task to altimate-code run. That pays for a second model and replaces the client's own reasoning loop.
• The tools themselves can only be used inside an altimate-code session. altimate-code is an MCP client only.

This PR adds altimate-code mcp serve, a stdio MCP server. Any MCP client, such as Claude Code, can call the data tools directly while its own model does the reasoning. The server never calls a model, so an MCP client's subscription covers the whole LLM cost.

What it exposes: five data tools, reusing the existing implementations, each with a short description:

• warehouse_list
• schema_inspect
• sql_execute
• sql_check
• sql_materialize

Added since the first revision:

• answer_commit (MCP only). The client's model commits its final answer through this tool. It runs the same requested-item and number-provenance checks as the native analyst, and returns a FINAL ANSWER: line for the model to reply with. It returns plain text only: Claude Code shows structuredContent to the model in place of the text, and the model then rewrote the answer as prose.
• Server instructions: the analyst method, 723 characters, sent in the initialize response.
• analyze prompt: interactive clients show it as a slash command.
• Reading question (elicitation): when a commit lists two readings and the client supports elicitation, the server asks once which reading the user meant. If the user picks the other reading, the commit is rejected and the model recomputes under it. The question times out after 20 s and follows the tool call's abort signal, so a client that never answers cannot stall the commit. Decline, cancel and timeout all keep the commit accepted.
• resource_link: when sql_execute spills a large result to a file, the result also carries a link to that file.

Behaviour:

• Read-only by default. Writes request the sql_execute_write permission, which the server denies unless it was started with --allow-write. Reads are auto-allowed. sql_materialize still requires a read-only source query and writes only to the server session's temporary scratch warehouse, which is removed on exit.
• Clean results. A local session is bound at start-up, so results no longer carry the "Not routed through the bound workspace" notice.
• Cancellation. An MCP request's abort is forwarded into the tool call.
• Client-neutral hints. Spill-file hints say "open this path with any file reader" instead of naming the agent-only read tool. This applies only on the MCP path, through a context flag, so normal agent output is unchanged.
• Connections. --connections <file> points at a connections file; without it, the server uses normal connection discovery.
• Config and flags like the agent. tool_output limits are read from the agent loader's files, order and variables (ConfigPaths, ALTIMATE_CLI_* names, {env:...} substitution), stopping at the git worktree; an unreadable file is skipped. --log-level, --print-logs, --integrations and --pure apply to mcp serve.
• Scratch writes in read-only mode. Without --allow-write, source connections stay read-only, but table writes to the session's own scratch warehouse work, as they do in the agent.
• Malformed connections. A discovered connection without a string type no longer stops startup or warehouse_list.
• Clean protocol. stdout carries only MCP protocol messages; logs go to stderr. The CLI's start-up middleware (banner, telemetry, agent init) is skipped for mcp serve only. Cold start is about 1.5 s.

Shared files touched:

File	Change
cli/cmd/mcp.ts	new serve subcommand (marked)
index.ts	middleware skip for mcp serve only, after the global flags (marked)
tool/truncate.ts	makeLayer for per-server output dirs, limits and hints (marked)
workspace/precedence.ts	bindLocalSession / releaseLocalSession helpers
sql-execute.ts, sql-result-format.ts	the mcpClient hint flag

Normal agent behaviour is unchanged.

Docs: a new "Use Altimate Code tools from another MCP client" section in docs/docs/configure/mcp-servers.md.

How did you verify your code works?

• Unit and integration: bun test on test/altimate/mcp-server plus every suite that references the shared files touched: 2,696 pass, 0 fail. The MCP tests run a real in-process MCP client and a stdio client against a temporary database. They:
  • list the 5 tools;
  • run warehouse_list, schema_inspect and sql_execute;
  • check a mutating sql_execute is refused by default and allowed with --allow-write;
  • check the routing notice is absent;
  • check cancellation works.
• Typecheck and markers: bun run typecheck is clean, and the marker check script/upstream/analyze.ts --markers --base main --strict passes.
• End to end with the real Claude Code CLI (2.1.302, Sonnet):
  • Setup: claude -p with --mcp-config pointing at altimate-code mcp serve from this branch, --strict-mcp-config, and Bash disallowed. The database was a 60-row SQLite orders table.
  • The server reported connected.
  • Claude called warehouse_list, schema_inspect and sql_execute, and answered correctly: 30 paid orders totalling 12,555, checked by hand.
  • A requested DELETE was refused with Permission denied: sql_execute_write. Restart with --allow-write to enable writes.
  • Cost: $0.09.
• Not run: Postgres, Snowflake and other remote warehouses through the MCP path. They reuse the same tool implementations and connection registry.

Cost side effects

The server never calls a model. Automatic queries are bounded: the startup connection list and warehouse_list profile only local SQLite/DuckDB catalogs (at most 50 tables, 3 to 5 second budgets) and run no queries on remote engines; sql_execute batches are capped at 8 queries with a shared output budget. Everything else runs only the SQL the client sends.

Screenshots / recordings

Not a UI change.

Checklist

• I have tested my changes locally
• I have not included unrelated changes in this PR
• I checked for cost side effects (model calls, queries or cloud resources that grow with user data) and described them, or wrote "none"

Note

Medium Risk
New SQL execution surface over MCP with read-only defaults and permission gating, but it reuses core query paths and misconfiguration or --allow-write could allow mutations against configured warehouses.

Overview
Adds altimate-code mcp serve, a stdio MCP server so external MCP clients can call Altimate’s five warehouse tools (warehouse_list, schema_inspect, sql_execute, sql_check, sql_materialize) without starting an agent or calling a model. A thin adapter wires the existing tool implementations with a local session, MCP-specific permissions, and client-neutral truncation/spill hints.

Safety and behavior: Source SQL writes are denied unless --allow-write; otherwise reads propagate forceReadOnly through dispatch so Postgres/SQLite/DuckDB get database-level protection, with stderr/warehouse_list caveats for classification-only engines. Optional --connections loads an isolated connections file via Registry.loadFile. Stdio keeps protocol on stdout; CLI middleware (telemetry/heap) is skipped for mcp serve. Scratch materialization and private spill directories are torn down on shutdown; MCP abort signals cancel in-flight queries.

Supporting changes: Truncate.makeLayer for per-server output dirs; docs for client setup; CI runs MCP server tests in a separate process with real drivers (ALTIMATE_MCP_E2E).

Summary by cubic

Opens altimate-code mcp serve, a stdio MCP server that exposes altimate-code's data tools to MCP clients without calling a model, so the client's own model does the reasoning and its subscription covers the LLM cost.

• Exposes warehouse_list, warehouse_add, sql_execute, sql_materialize and answer_commit by default; schema_inspect and sql_check only with --all-tools. All reuse existing implementations.
• schema_inspect without a table lists schemas with table counts, then up to 500 tables per schema via pushed-down catalog queries; row counts are local SQLite/DuckDB only (at most 50 tables under a 3-second budget). Remote engines show catalog estimates, never COUNT(*).
• warehouse_list adds local tables with columns and a one-row sample (SQLite and local DuckDB base tables only), bounded by table budgets and a 4-second deadline; remote connections run no queries. An empty registry names candidates from env-var and dbt-profile detection (type and source only, never values); a connection without a string type no longer crashes discovery.
• sql_execute describes tables when tables is given and then runs query/queries/query_from in the same response. It accepts up to 8 read-only queries per call as one labeled block each with a shared byte/line budget; a failing item does not stop the rest. A later step can reference an earlier one via {{label.column}} (bare comma-separated literals that fit IN (...), DuckDB lists and MongoDB arrays, at most 1,000 rows) or {{label}} (scratch table); a bad reference fails only that step. A result too large to show inline becomes a scratch table result_N with a 10-row preview and a hint; the full rows spill to a CSV copy in a private per-process directory deleted on close.
• answer_commit requires every requested item to map to its own field or rows column (at most two rejections per turn) and once per commit rejects a result with fewer items than the request asks for, counting non-blank asked labels when given so a rows commit is checked too; an unchanged recommit is accepted. MCP commits skip the number-provenance warning, which the server cannot verify for numbers computed in the client; native sessions keep it. The user's question is passed verbatim as an MCP-only request argument, stripped before parsing. Complete commits return a basis plus an answer-only FINAL ANSWER: line; under-asked commits keep the earlier rendering. When a commit records two readings it asks once per session which reading was meant, with a 20-second timeout that follows the tool call's signal; decline or timeout leaves the commit accepted.
• warehouse_add lets an empty session add connections; in MCP mode it skips post-connect suggestions for tools the toolkit lacks, a read-only session refuses create: true, and a store whose file or directory is not writable is auto-opened read-only.
• Read-only by default; writes need --allow-write. Without it, source queries request database-enforced read-only on Postgres, SQLite and DuckDB; other engines are classification-only, so the server warns to use a read-only database user. sql_materialize writes only to a session-local scratch warehouse removed on exit.
• Forwards MCP cancellation to tool calls, binds a local session so results lack the routing notice, and sends analyst-method instructions that end with a FINAL ANSWER: line, making answer_commit optional; the instructions also list connections known at startup (name, type and table names for small local catalogs), so local connectors open when the server starts, plus an analyze prompt for interactive clients. Advertised tool schemas are compacted for the client without changing parsing. Output limits resolve through the agent's config loader with {env:...} substitution. Writes only MCP frames to stdout with logs on stderr; --print-logs/--log-level/--integrations/--pure apply and telemetry startup is skipped.
• --connections <file> is the sole source of connections and rejects the reserved scratch name; otherwise normal discovery applies, with registry state kept per project directory and config re-read from sources while empty. The warehouse_list no-connections hint names the real global/project config paths and ALTIMATE_CODE_CONN_* variables. The stdio server is driven over raw JSON-RPC in tests.
• The analyst requests high reasoning effort on adaptive-thinking models when neither the request nor agent config chooses one; ALTIMATE_ANALYST_EFFORT overrides it or turns it off.

Summary by CodeRabbit

• New Features
  • Added a standalone MCP server that gives MCP clients access to five Altimate tools for warehouse discovery, schema inspection, SQL execution, SQL checks, and materialization.
  • Supports an optional connections file. SQL writes are disabled by default; enabling them remains subject to safety checks. Materialization uses a read-only source query and a temporary scratch destination.
  • Large results can be opened from a local file path, with temporary output cleaned up when the client closes.
• Documentation
  • Added setup instructions, connection-source details, tool descriptions, write-permission guidance, output limits, and notes on read-only enforcement.

Update: answer_commit over MCP (stacked on #native commit 15d2766)

This branch now merges 15d2766115 (the native feat/analyst-commit-slots-effort commit, no PR of its own) so the server reuses answer-commit-checks.ts instead of a copy. Until that commit lands on main, this PR's diff includes it; the MCP-specific change is the last two commits.

• New sixth tool answer_commit: asked-item coverage (at most two rejections per turn), one-time number-provenance warning, canonical FINAL ANSWER: <text> result. The adapter keeps session history (tool outputs and rejections) in the shape the shared checks read, and starts a new turn after an accepted commit.
• The 400-character basis limit is not enforced over MCP: longer text is trimmed to 400 characters instead of rejected. The native tool is unchanged.
• Server instructions step 7 now points at answer_commit.
• Help snapshot updated for mcp serve.

Tests: ALTIMATE_MCP_E2E=1 bun test test/altimate/mcp-server 33 pass, 0 fail ("Ran 33 tests across 2 files"); typecheck clean; marker check ok. Full package run: 20221 tests, 19335 pass, 18 fail, 790 skip, 78 todo; after the snapshot fix, the remaining failures (mcp.headers, HttpApi status/experimental, --time-budget run tests, and a few environment-dependent suites) fail identically on the native branch without these commits. Codex read-only review of the MCP diff: no P0/P1.

Update 2026-10-20 (head 873d18a)

• Compound requests: the compact answer_commit description again carries the two-field rule and its example (e544a58).
• Setup from zero: includes the cherry-picked fix: point the warehouse_list no-connections hint at the real config locations #1559/fix: keep warehouse connection registry state per project directory #1567 (per-project registry, re-read while empty, real-path hint). warehouse_add is exposed; an empty warehouse_list names env-var / dbt-profile candidates (no values); a read-only session refuses create: true; an added store this process cannot write is opened read-only.
• Fewer round trips: sql_execute takes tables (describe tables and run queries in one call). The default toolset is five tools (warehouse_list, warehouse_add, sql_execute, sql_materialize, answer_commit); --all-tools restores schema_inspect and sql_check. Definitions plus instructions 5.7k chars (was 6.7k). Companion plugin change: feat(altimate-code): experimental direct MCP data tools (Claude reasons, altimate-code supplies tools) altimate-claude-plugin#6 (40a4fe2).
• Verification: ALTIMATE_MCP_E2E=1 bun test test/altimate/mcp-server/ plus the registry/hint suites (113 pass), bun test test/altimate/ (9,748 pass; the 2 failing datamate-list-integrations tests fail at the base commit too), typecheck clean. Local Codex reviews at 1ee2d31, 2f2ff27 and d4abef2: no P0/P1; P2s fixed except the combined size of a fused 8-table response (bounded by 8 per-tool output budgets).
• Measured in Claude Code (internal eval, 5 trials per question): accuracy unchanged; first request -408 tokens. Turns and cost per run did not fall. Data questions with a configured connection still cost more than plain Claude Code; with no connection configured the plugin now reaches the data through MCP in the database-backed case and is at cost parity.

Update 2026-10-21 (head 24b4538)

• Shorter sql_execute / sql_materialize property descriptions (tool JSON 5,163 -> 4,824 chars); parsing unchanged. Companion plugin cuts (agent, skills, hook) are in feat(altimate-code): experimental direct MCP data tools (Claude reasons, altimate-code supplies tools) altimate-claude-plugin#6.
• Local Codex review at 24b4538: no P0/P1. Open P2s (follow-up): restore "read-only" in the queries description, the one-string-column rule for query_from, and the budget/saved-rows note for full_text_columns; P3: allowed target_table characters.
• Internal eval (5 trials per question, 12 questions): with the slimmer plugin the first request is within ~0.5k tokens of plain Claude Code (was ~5k), accuracy held, cost per run 7% lower than before but still above plain Claude Code.

Update 2026-10-21 (head 07b3c80): chained batch steps

• In a sql_execute queries batch, a later step can use an earlier step's rows: IN ({{label.column}}) expands to that step's values as quoted, comma-separated literals (source step capped at 1,000 rows; NULL when empty; JSON values for MongoDB), and {{label}} to a scratch table with its rows (steps on scratch). A reference to a failed, missing or oversized step fails only that step; the rest still run. Descriptions +~130 chars.
• 07b3c80 fixes the first version (b9dbc21), which wrapped the values in parentheses; IN ({{x}}) and DuckDB lists then failed.
• Tests: server.test.ts (ALTIMATE_MCP_E2E=1) same-connection chain, cross-connection list + scratch join, over-cap list, mid-batch error, DuckDB list, empty step. Local Codex reviews at b9dbc21 and 07b3c80: no P0/P1. Open P2s: {{word}} inside SQL string literals is treated as a reference; dialect-specific quoting uses the generic form when warehouse is omitted; an explicit limit above 1,000 bypasses the row cap; labels with spaces cannot be referenced.
• Internal eval (5 trials per question): chaining was used in a minority of runs; turns and cost per run moved little.

Update 2026-10-21 (head 496359b): fewer fixed round trips

• 4c8490f: the initialize instructions end with the connection list known at startup (names, types, table names of small local catalogs; at most 1,200 bytes; a large catalog is listed by name only). warehouse_list stays for refreshes, columns and sample rows. Local connectors now open at server start.
• 496359b: answer_commit is optional; the analyst method ends with a FINAL ANSWER: line naming every requested item.
• Local Codex review at 496359b: no P0/P1. Open P2s: the startup listing is not interruptible by its 5 s timeout while a connector is connecting; it runs the same per-table row count that warehouse_list discovery runs; the byte reservation counts characters, not bytes. P3: the answer_commit description still says "call last".
• Internal eval (5 trials per question, 12 questions): connection and commit calls dropped to ~0 per run; cost per run -23% vs the previous build, now at parity with plain Claude Code overall; accuracy held.

Update 2026-10-21: own task set on a real warehouse (head 496359b, no code change)

• 10 questions of our own on BigQuery (19M-row partitioned events table) plus Postgres, 3 trials per question, plain Claude Code against this build with the plugin: accuracy 30/30 against 30/30. Cost per run was 17% lower with the plugin ($0.066 against $0.080). BigQuery bytes billed per run were 68% lower overall and 79% lower on large-table questions. Median time was at parity. Neither arm pulled raw personal data into context.
• With no connections configured, the model used warehouse_add in 4 of 9 runs. In the other 5 it fell back to Python clients via Bash. All 9 passed.
• Finding: a BigQuery service account with dataset-level roles only cannot list schemas (the region INFORMATION_SCHEMA needs project-level bigquery.metadataViewer). The minimum role should be documented as a follow-up.

Review status (head 79839d4)

Merged main (11bfb29). Review threads from Kilo, CodeRabbit and cubic are addressed in e65cfa5 and 79839d4. Local Codex review at e65cfa5 (no P0/P1; its two P2s were fixed in 79839d4) and at 79839d4 (no findings). Tests: ALTIMATE_MCP_E2E=1 bun test test/altimate/mcp-server/server.test.ts 70 pass; bun test test/altimate/tools test/altimate/mcp-server test/altimate/connections and related suites 1,438 pass, 1 fail (datamate-list-integrations, which fails at the previous head too); typecheck clean; marker check ok.

📝 Walkthrough

Adds a standalone stdio MCP server for five Altimate tools. The CLI accepts an optional connections file and disables SQL writes by default. The server handles tool calls, applies read-only controls, and closes active work and local resources during shutdown.

Changes: Altimate MCP server

Layer / File(s)	Summary
Connection and query controls packages/opencode/src/altimate/native/connections/*, packages/opencode/src/altimate/native/query-execution.ts, packages/opencode/src/altimate/tools/*	The server can load and validate an explicit connections file. MCP context can force read-only execution through SQL, schema, and materialization tools. Warehouse listings include caveats for connection types without database-enforced read-only protection.
MCP adapter and server lifecycle packages/opencode/src/altimate/mcp-server/*, packages/opencode/src/altimate/workspace/precedence.ts, packages/opencode/src/tool/truncate.ts, packages/opencode/src/altimate/tools/sql-result-format.ts	The adapter creates a local session for five tools, applies write permissions, and tracks active calls. Output limits and spill hints can be configured for MCP. Server shutdown aborts active calls and releases session and temporary output resources.
CLI integration and validation packages/opencode/src/cli/cmd/mcp.ts, packages/opencode/src/index.ts, docs/docs/configure/mcp-servers.md, packages/opencode/test/altimate/mcp-server/*, .github/workflows/ci.yml	The CLI registers mcp serve with optional connection and write settings. Middleware skips remaining startup work for that command. Documentation and integration tests cover configuration, tool behavior, write controls, output handling, and shutdown.

Review comments at @packages/opencode/src/altimate/mcp-server/adapter.ts:
- Around line 33-40: Update the truncation writer in the adapter to lazily
create a unique per-session spill directory under the temporary directory using
a secure temporary-directory API, then write result files there. Update the
adapter’s close() method to remove that directory recursively after releasing
session resources, ensuring cleanup occurs when no spill directory was created
as well.

Review comments at @packages/opencode/src/altimate/mcp-server/server.ts:
- Around line 43-47: Update the `inputSchema` mapping in the adapter so
`sql_execute`’s `full_text_columns` description does not direct MCP clients to a
nonexistent `read` tool; make the recovery guidance client-neutral and
consistent with the runtime spill hint.

Review comments at @packages/opencode/src/index.ts:
- Line 139: Move the `opts.printLogs` handling in the middleware before the
early return for `mcp serve`, so `OPENCODE_PRINT_LOGS` is set for that command.
Leave the `opts.logLevel` handling unchanged.
