## Installation

### Installing via Smithery

To install Code Research Server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/@nahmanmate/code-research-mcp-server):

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

### Manual Installation
1. Clone the repository and install dependencies:
```bash
git clone https://github.com/nahmanmate/code-research-mcp-server.git
cd code-research-server
npm install
```

2. Build the server:
```bash
npm run build
```

3. Configure MCP Settings:

Add the server configuration to your MCP settings file:

- VSCode: `~/.vscode-server/data/User/globalStorage/rooveterinaryinc.roo-cline/settings/cline_mcp_settings.json`
- Claude Desktop:
  - MacOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
  - Windows: `%APPDATA%/Claude/claude_desktop_config.json`

```json
{
  "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": []
    }
  }
}
```

Note: 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:
```bash
npm run watch
```

### Error Handling

The server implements robust error handling:
- 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

Since MCP servers communicate over stdio, debugging can be challenging. Use the MCP Inspector for detailed request/response monitoring:

```bash
npm run inspector
```

The Inspector provides:
- Real-time request/response monitoring
- Tool execution tracing
- Error stack traces
- Performance metrics

Visit the provided URL in your browser to access the debugging interface.

### Caching

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