AstAnalyzer

AstAnalyzer is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from angrysky56/ast-mcp-server. Its token cost is not measured, scanned A, original, MIT.

A local MCP server for analysing abstract syntax trees, which are structured representations of source code. It runs a server program from a specified project directory.

In plain words
What is it for?
Analysing source-code structure through AST-based tools.
Why use it?
It gives an AI coding assistant a way to inspect code structure rather than relying only on raw text.

MCP server for Claude CodeCodexCursorGemini CLIOpenCode

Written for no agent in particular: it speaks MCP, so any client can run it. Also seen: listed in a Claude config.

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /home/ty/Repositories/ai_workspace/ast-mcp-server/ast_mcp_server.

Getting it into your agent

Security

Grade A, and why

AstAnalyzer 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 6d 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.
