Debugging

Since MCP servers communicate over stdio, debugging can be challenging. The project includes the MCP Inspector for debugging:

npm run inspector

This will provide a URL to access debugging tools in your browser.

Error Handling

The server includes comprehensive error handling for:

Invalid API keys
Missing required parameters
Linear API errors
Invalid tool requests

All errors are properly formatted and returned with descriptive messages to help diagnose issues.

Technical Details

Built with:

TypeScript
Linear SDK (@linear/sdk v37.0.0)
MCP SDK (@modelcontextprotocol/sdk v0.6.0)

The server uses stdio for communication and implements the Model Context Protocol for seamless integration with AI agents.
