ast-mcp-server AGENTS.md

ast-mcp-server AGENTS.md is an instructions file for Codex, OpenCode from yailPeralta/ast-mcp-server. It costs 50 tokens per session, scanned A, original, ISC.

Repository instructions for an abstract-syntax-tree server. An abstract syntax tree is a structured representation of source code that tools can inspect, and an MCP server lets an AI agent call external tools through a standard interface.

In plain words
What is it for?
Read them when working on this repository to find the GitHub Issues workflow and the documentation describing its domain structure.
Why use it?
They point agents to the correct issue-tracking and domain documentation instead of leaving project-specific procedures unclear.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ast-mcp-server AGENTS.md 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 5d 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.
