typescript-definition-finder-mcp

The TypeScript Definition Finder MCP Server is a specialized tool designed to assist AI code editors in locating the original definitions of TypeScript symbols within a codebase. This server is particularly beneficial for developers working with TypeScript projects, as it can identify the source of imported symbols, classes, interfaces, or functions. By providing both the location and a code snippet of the definition, it enhances the efficiency of code navigation and understanding. The server operates via a stdio interface, allowing seamless integration with various AI code editors. It requires a TypeScript project setup and Node.js for execution. The server can be installed using Smithery and is compatible with several AI code editors, including Claude Desktop, Cursor, Windsurf, and Roo Cline Editor.
