 - **Unified MCP endpoint at `/mcp`**: the extension server itself is an MCP server (streamable HTTP) aggregating every tool/resource/prompt of every enabled and running managed server, deterministically namespaced `<server>__<name>`. Upstream failures come back as tool errors, never protocol crashes; `listChanged` fires when upstreams change. Auth is the same bearer token Cate injects. The panel's Endpoint card shows the URL and header with copy buttons; point any MCP client (including a coding agent) at it.
 
-- **One-click install into coding agents**: the Endpoint screen writes this endpoint into each agent's workspace-local config — Cate Agent (`.pi/mcp.json`, read by the `pi-mcp-adapter` package), Claude Code (`.mcp.json`), Cursor (`.cursor/mcp.json`), OpenCode (`opencode.json`), and Codex (`.codex/config.toml`), each in that agent's own shape, preserving every other key. Antigravity (global-only config) and PI (no MCP) are listed but disabled with the reason. The endpoint's port/token are reminted each Cate session, so an install is a snapshot: a stale entry is flagged with an Update button, and the endpoint only serves while the panel is open.

 - **Discover tab**: searches the official registry at `registry.modelcontextprotocol.io` (`GET /v0/servers?search=…` with cursor pagination) and one-click prefills the add-server form from a registry entry's npm/pypi/oci package or remote URL. Registry failures stay inside that tab.
