Bear Notes MCP Server is an unofficial Model Context Protocol server for the Bear note taking app on macOS, written in TypeScript and shipped both as a one click mcpb extension for Claude Desktop and as the bear-notes-mcp npm package for any stdio client, including Claude Code, Codex, Gemini, Cursor and Windsurf. Its defining choice is relevance ranked search rather than substring matching: queries are scored across note titles, bodies, hierarchical tags and text that Bear extracted from attached images and PDFs through OCR, and every hit comes back with a context snippet. Filters for tag, date range and pinned state can be combined with a search term or used on their own to browse, and dates accept relative expressions such as yesterday, last week or start of last month. Hierarchical tag matching rolls subtags up automatically. Reads go straight against the Bear SQLite database through the native node:sqlite module, so lookups work without launching Bear and without unsigned third party binaries, while writes are routed through the Bear URL handler so the application validates and applies them atomically. The server is read only by default with four tools enabled, namely search, open note, list tags as a tree with note counts, and find untagged notes. An opt in edit mode adds eight more for creating notes, appending or replacing text either wholesale or at a named section heading, attaching local files up to 25 MB with symlinks rejected, adding tags, archiving notes and renaming or deleting a tag across the entire library. Write tools require the current revision token of the note and reject stale writes with an instruction to re read the note first, which guards against clobbering concurrent edits. The server makes no network calls and reports no telemetry, so everything stays on the local machine.
