MCP-Grep is a Python-based server that exposes grep capabilities through the Model Context Protocol (MCP), enabling large language models and other MCP clients to perform text search operations against files and directories. It provides a resource grep://info that returns metadata about the system grep binary (path, version, and supported features) and a tool named grep that performs pattern matching using the system grep. The server can be installed via pip or via Smithery, and runs as mcp-grep-server or, for interactive debugging, mcp-grep-inspector. Key features include discovering the grep binary specifics, performing regex-based searches across files, and supporting common grep options such as case-insensitive matching, showing context lines, limiting results, and fixed-string searches, plus recursive directory traversal. It also supports natural language prompts to simplify queries for LLMs and offers MCP Inspector integration for interactive debugging and testing, including exploring resources, testing queries with different parameters, and viewing formatted results.
