It gives an agent structured symbol lookups instead of making repeated text searches through a large repository. That makes questions about definitions, references, and call relationships more targeted.

gtags

gtags is an MCP server for Claude Code from harshithsunku/mcp-gtags-server. Its token cost is not measured, scanned A, original, MIT.

An MCP connection for coding agents to query a GNU Global index of C and C++ code. MCP is a standard way for an agent to call tools provided by another local service.

In plain words

What is it for?: Use it to find who calls a function, where it is defined, how it is used, and which call paths connect two functions in a large C or C++ project.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe. Third-party audits

Security

Grade A, and why

gtags scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
