Clone the repository: ```bash git clone https://github.com/yourusername/needle-mcp.git ``` 2. Install UV globally using Homebrew in Terminal: ```bash brew install uv ``` 3. Create claude_desktop_config.json: - For MacOS: Open directory `~/Library/Application Support/Claude/` and create the file inside it - For Windows: Open directory `%APPDATA%/Claude/` and create the file inside it 4. Add this configuration to claude_desktop_config.json: ```json { "mcpServers": { "needle_mcp": { "command": "uv", "args": [ "--directory", "/path/to/needle-mcp", "run", "needle-mcp" ], "env": { "NEEDLE_API_KEY": "your_needle_api_key" } } } } ``` 5. Get your Needle API key from needle.xyz 6. Update the config file: - Replace `/path/to/needle-mcp` with your actual repository path - Add your Needle API key 7. Quit Claude completely and reopen it ## Usage Examples * "Create a new collection called 'Technical Docs'" * "Add this document to the collection, which is https://needle-ai.com" * "Search the collection for information about AI" * "List all my collections" ## Troubleshooting If not working: - Make sure UV is installed globally (if not, uninstall with `pip uninstall uv` and reinstall with `brew install uv`) - Or find UV path with `which uv` and replace `"command": "uv"` with the full path - Verify your Needle API key is correct - Check if the needle-mcp path in config matches your actual repository location ### Reset Claude Desktop Configuration If you're seeing old configurations or the integration isn't working: 1. Find all Claude Desktop config files: ```bash find / -name "claude_desktop_config.json" 2>/dev/null ``` 2. Remove all Claude Desktop data: - On MacOS: `rm -rf ~/Library/Application\ Support/Claude/*` - On Windows: Delete contents of `%APPDATA%/Claude/` 3. Create a fresh config with only Needle: ``` mkdir -p ~/Library/Application\ Support/Claude cat > ~/Library/Application\ Support/Claude/claude_desktop_config.json << 'EOL' { "mcpServers": { "needle_mcp": { "command": "uv", "args": [ "--directory", "/path/to/needle-mcp", "run", "needle-mcp" ], "env": { "NEEDLE_API_KEY": "your_needle_api_key" } } } } EOL ``` 4. Completely quit Claude Desktop (Command+Q on Mac) and relaunch it 5. If you still see old configurations: - Check for additional config files in other locations - Try clearing browser cache if using web version - Verify the config file is being read from the correct location
