crawlee-mcp: Instructions file for Codex

AGENTS.md

crawlee-mcp AGENTS.md is an instructions file for Codex, OpenCode from patrikmichi/crawlee-mcp. It costs 499 tokens per session, scanned A, original, MIT.

A set of agent instructions for a local MCP server that fetches and scrapes web pages with Crawlee, a Node.js web-crawling library. It documents tools for fetching pages, fetching several URLs, taking screenshots, and checking server health.

In plain words
What is it for?
Use it to fetch one or many URLs, render JavaScript-heavy pages, take screenshots, or configure optional proxies, timeouts, and stealth mode. The server runs locally over standard input and output.
Why use it?
It tells an agent how to use the server and what each web task returns, including clean Markdown, errors, and PNG screenshots.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md.

This is patrikmichi/crawlee-mcp's own configuration. It tells Codex and OpenCode how to work on crawlee-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything crawlee-mcp configures →

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

crawlee-mcp 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 7d 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.
