typeprobe MCP

An MCP server that queries the TypeScript compiler to provide inferred types, completions, and type errors to AI coding agents. It supports tools like hover_by_name, diagnostics, and completions, enabling agents to understand code structure without guessing. It also offers a testing library for snapshot testing inferred types.
