An unofficial, opinionated MCP server for Bear Notes — built around relevance-ranked search instead of substring matching. Results come ranked across titles, bodies, and hierarchical tags, with snippets and combinable filters (tag, date, pinned). Reads run direct against Bear's SQLite database — no Bear app required for queries.

Writes route through Bear's own URL handler — atomic and validated by Bear. Offline-first: no network calls, no telemetry, all processing on your Mac. Works with any MCP client — Claude Desktop, Claude Code, Codex, Gemini, Cursor. Ships as a one-click .mcpb extension or a standalone npm package.

Example prompts:

Find the deep-dive I wrote on export pipelines, somewhere under #engineering/
Append today's decisions to the 'Decisions' section of my Weekly Ops note
Pull every note under #research/llm-evals into a survey outline
Find my notes tagged #blog/drafts and draft this week's post outline

✨ Key Features

  • Read-only by default — flip Edit Mode for writes. 4 tools always on (search, open, find untagged, list tags); 8 more in Edit Mode for create, edit, attach, tag, archive
  • Relevance-ranked search across titles, bodies, and tags — finds the right note, not just the ones that contained your literal words
  • Date-based search with relative dates ("yesterday", "last week", "start of la

Questions

What is the Bear Notes MCP server?

MCP Server for Bear note taking app available as Claude Desktop extension or standalone server for any other AI tool

What tools does Bear Notes expose?

13 in total: 7 read-only, 5 that write, and 1 that can delete or overwrite (bear-delete-tag). Every one is listed on this page with its risk.

Is Bear Notes safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B. Separately from the audit: 1 of its tools can destroy data, so scope the token you give it to what you actually need.

What credentials does Bear Notes need?

No credential environment variables were found in its source, so it appears to need none.

How does Bear Notes run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as bear-mcp-site at 0.0.1.

How current is this page?

The grade is for one exact copy of the source (2fca836319d8), read on 2026-10-06. The repository is watched and re-audited when it changes.
