Example Usage

Here are examples of how to interact with the Bear MCP tools through AI assistants:

Searching for Notes

Ask your AI assistant to search for notes containing specific terms:

Can you find all my notes about "project management"?

Opening a Specific Note

Ask your AI assistant to retrieve a specific note by title:

Show me my note titled "Meeting Notes - March 2025"

Viewing Tags

Ask your AI assistant to list all your Bear tags:

What tags do I have in my Bear notes?

Finding Notes with a Specific Tag

Ask your AI assistant to show notes with a particular tag:

Show me all notes with the #work tag

Advanced Options

If your Bear database is in a non-standard location:

npx github:bart6114/my-bear-mcp-server --db-path /path/to/your/database.sqlite

Technical Details

Read-Only Implementation

This MCP server connects to your Bear SQLite database using a strict read-only connection. This is enforced at the database driver level:

// From src/bear-db.ts
this.db = new Database(dbPath, { readonly: true });

This ensures that:

• No write operations can be performed on your database
• Your notes and tags cannot be modified, deleted, or corrupted
• The database connection will fail if write permissions are attempted

All operations performed by this server are SELECT queries that only retrieve data without modifying it.
