Description

This server implements a Model Context Protocol (MCP) tool that scans source files and returns line numbers where a given function name appears. It supports Python and TypeScript/TSX files and uses regex-based pattern matching to locate function usages. It's intended for integrating with MCP-compatible assistants (e.g., Copilot, Claude) to provide quick code references and aid code analysis workflows.
