Development Notes

This utility employs TypeScript and leverages the Model Context Protocol SDK to construct a server capable of communicating with the Claude AI environment. Modifications to the available functions or the introduction of novel API endpoints necessitate editing the src/index.ts file followed by a project rebuild.
