Bear MCP Server: Data Access for AI Applications

Overview: What is Bear MCP Server?

Bear MCP Server is a specialized Model Context Protocol (MCP) server designed to provide seamless access to data stored in the Bear Notes application, specifically targeting the SQLite database where these notes are stored. This server acts as an intermediary, enabling various AI applications, such as Claude Desktop, Continue, and Cursor, to interact with user-generated content from Bear Notes through a standardized protocol. By leveraging the capabilities of MCP, this project aims to facilitate broader integrations and data access scenarios in the realm of AI applications.

🔧 Core Features & MCP Capabilities

Bear MCP Server supports essential operations that ensure smooth integration with various AI tools:

• Retrieve All Notes: The server provides an MCP endpoint labeled get_notes for AI applications to fetch all notes stored in the Bear database.
• Search Notes by Text: Users can search through their notes using keywords, which is facilitated via the get_notes_like command that supports text-based filtering of notes based on specific criteria.
• List All Tags: Tag management is another crucial feature provided by this server under the label get_tags, allowing AI applications to retrieve and categorize content effectively.

These features are integrated into MCP's request-response model, ensuring compatibility with multiple clients such as Claude Desktop, Continue, and Cursor. The implementation of these commands adheres strictly to the MCP protocol guidelines, maintaining data integrity and security standards during interactions.

⚙️ MCP Architecture & Protocol Implementation

The architecture of Bear MCP Server is designed to be modular and scalable while being fully compliant with MCP's architectural principles:

• Data Layer: The core data layer uses SQLite to store and manage notes, ensuring reliable and efficient local database operations.
• MCP Handler Module: This module translates requests from the AI applications into SQL commands tailored for interacting with the Bear Notes SQLite database. It ensures that each command is executed efficiently without compromising on performance or data security.

The protocol implementation involves conforming to MCP's guidelines for client-server interactions, ensuring that all transactions are secure and efficient. Additionally, this design supports future extensions by maintaining a flexible architecture that can accommodate additional features as needed.

🚀 Getting Started with Installation

To set up the Bear MCP Server on your system:

# Clone the project
git clone https://github.com/akseyh/bear-mcp-server

# Change directory
cd bear-mcp-server

# Install dependencies
npm install

# Build the project
npm run build

💡 Key Use Cases in AI Workflows

Use Case 1: Note-Based Conversational AI

Imagine a scenario where an AI assistant, like Claude Desktop, uses Bear MCP Server to retrieve and analyze user notes. By accessing these notes via MCP commands (get_notes, get_tags), the AI can provide contextually relevant responses or insights based on the content of the notes. This integration enables a more personalized and accurate conversational experience.

Use Case 2: Content Categorization for Personal Knowledge Management

In an enterprise setting, Bear MCP Server can be integrated with an internal knowledge management system to categorize user-generated content using tags from Bear Notes. By utilizing the get_tags endpoint, such systems can automatically tag documents or emails, making them easily searchable and organized according to keywords and labels used in notes.

🔌 Integration with MCP Clients

The following table provides a detailed compatibility matrix for various MCP clients:

MCP Client	Resources	Tools	Prompts
Claude Desktop	✅	✅	✅
Continue	✅	✅	✅
Cursor	❌	✅	❌

This matrix indicates that Bear MCP Server currently supports full integration with both resources and tools for all listed clients, ensuring a versatile interoperability.

📊 Performance & Compatibility Matrix

Bear MCP Server is optimized for performance while maintaining backward compatibility:

• Response Time: The server minimizes latency by executing SQL queries efficiently after receiving requests.
• Error Handling: Robust error handling mechanisms ensure that invalid commands or data in the request are gracefully managed without crashing.

This design ensures that the server can handle a wide variety of client interactions without compromising performance or user experience.

🛠️ Advanced Configuration & Security

For advanced configurations, you might need to customize your claude_desktop_config.json file:

{
  "mcpServers": {
    "bear": {
      "command": "node",
      "args": [".../build/index.js"] // Change it with your path
    }
  }
}

Ensure that the environment variables are set correctly, especially for sensitive data like API keys. This configuration ensures that each AI application has the necessary permissions and resources to interact effectively.
