Bear MCP Server: Your Personal Knowledge Base Meets AI

Stop context-switching between Bear and your AI assistant. This MCP server connects Claude directly to your Bear notes database, giving you instant access to your entire knowledge base during AI conversations.

The Problem Every Bear User Faces

You're deep in a Claude conversation about a project, and you know you have relevant notes in Bear. But to access them, you need to:

• Switch to Bear
• Search for the notes
• Copy/paste content back
• Lose conversation flow
• Repeat this dance constantly

Your personal knowledge base sits isolated from your AI workflows, creating friction exactly when you need seamless access.

Direct Database Access, Zero Friction

This MCP server connects straight to Bear's SQLite database with read-only access. Claude can now search your notes, pull up specific entries, and browse your tags without you lifting a finger.

What you get:

• Search across all your notes with natural language
• Open specific notes by title or ID
• Browse and filter by tags
• View tag hierarchies
• All from within Claude conversations

The read-only implementation means zero risk to your notes - it's physically impossible for this server to modify your Bear database.

Real-World Usage Scenarios

Project Research: "Show me all my notes about microservices architecture from the #backend-design tag"

Meeting Prep: "Pull up my notes from last month's client meetings about the dashboard redesign"

Knowledge Synthesis: "Find my notes about React performance optimization and summarize the key patterns I've documented"

Content Creation: "Look through my #writing-ideas notes and help me outline a blog post about developer productivity"

Dead Simple Setup

npx github:bart6114/my-bear-mcp-server

That's it. The server auto-discovers your Bear database and starts running.

For Claude Desktop, add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "bear": {
      "command": "npx",
      "args": ["github:bart6114/my-bear-mcp-server"]
    }
  }
}

Why This Approach Works

Direct SQLite Access: Bypasses Bear's API limitations for faster, more comprehensive queries

Read-Only Safety: Database connection enforced at the driver level - your notes remain untouchable

Zero Configuration: Auto-detects standard Bear database locations

Universal Compatibility: Works with Claude Desktop, VS Code extension, and any MCP-compatible client

Available Tools

• search_notes: Full-text search across your entire note collection
• open_note: Retrieve specific notes by title or unique ID
• get_tags: List all your Bear tags for browsing
• open_tag: View all notes associated with a specific tag

Each tool returns structured data that Claude can immediately work with - no manual formatting or cleanup needed.

Technical Implementation

Built on the Model Context Protocol with TypeScript, using better-sqlite3 for database access. The server enforces read-only connections at the SQLite driver level:

this.db = new Database(dbPath, { readonly: true });

This ensures that even if something goes wrong, your Bear database remains protected.
