Installation

Installing via Smithery

To install Code Research Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @nahmanmate/code-research-mcp-server --client claude

Manual Installation

  1. Clone the repository and install dependencies:
git clone https://github.com/nahmanmate/code-research-mcp-server.git
cd code-research-mcp-server
npm install
  1. Build the server:
npm run build
  1. Configure MCP Settings:

Add the server configuration to your MCP settings file.

Example configuration:

{
  "mcpServers": {
    "code-research": {
      "command": "node",
      "args": ["/absolute/path/to/code-research-mcp-server/build/index.js"],
      "env": {
        "GITHUB_TOKEN": "your_github_token"  // Optional: Prevents rate limiting
      },
      "disabled": false,
      "alwaysAllow": []
    }
  }
}

Replace /absolute/path/to with the actual path where you cloned the repository.

Development

Running in Development Mode

For development with auto-rebuild on changes:

npm run watch

Error Handling

The server implements robust error handling including:

  • API-specific error messages for each platform
  • Rate limit handling for GitHub API
  • Graceful fallbacks for service unavailability
  • Cached responses to reduce API load

Debugging

Use the MCP Inspector for detailed request/response monitoring:

npm run inspector

The Inspector provides:

  • Real-time request/response monitoring
  • Tool execution tracing
  • Error stack traces
  • Performance metrics

Caching

  • Results cached using node-cache
  • Default TTL: 1 hour
  • Separate cache keys per query/limit combination
  • Platform-specific caching strategies
  • Memory-efficient storage
