mcp-gtags-server

An MCP server that provides indexed C/C++ code navigation for AI agents using GNU Global (gtags). It replaces slow and noisy grep scans with fast, indexed lookups, offering ~100x faster query times and significantly less context noise. It supports kernel-scale codebases, handles #ifdef guards, and requires no sudo privileges or pre-installed toolchains, installing itself into user space.
