laver-mcp: Instructions file for Codex

AGENTS.md

laver-mcp AGENTS.md is an instructions file for Codex, OpenCode from Developyn/laver-mcp. It costs 574 tokens per session, scanned A, original, MIT.

A set of repository instructions for developing the Laver MCP server, a Node.js program whose tools call Laver's public web service. It covers development, testing, publishing, and Git rules.

In plain words
What is it for?
Use it when changing the server, running its local or live checks, starting it over standard input and output, or preparing updates for npm.
Why use it?
It tells coding agents where the real source code lives, which files are published, and how to check changes safely.

Instructions file for CodexOpenCode

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

This is Developyn/laver-mcp's own configuration. It tells Codex and OpenCode how to work on laver-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 laver-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

laver-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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 36 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — @laver/mcp

MCP server for Laver. Every tool is a thin call to the public REST API at https://api.laver.app; there is no local state and no second implementation of anything. See README.md for the tool list and setup.

This repository mirrors what is published to npm as @laver/mcp. server.js, README.md and LICENSE are the published files (see files in package.json); anything else here is repo-only and does not ship.

Development

Source of truth for the server is the private Laver monorepo at mcp/. Changes land there, are published to npm, and are mirrored here — do not fix a bug only in this repo, or the next publish reverts it.

Command Purpose
npm run check Full check suite against a stub API
npm run check:live Same suite against the live API (needs LAVER_API_KEY)
npm start Run the server on stdio

Node 24 is the floor in engines.

The Dockerfile is repo-only and is not published to npm. It exists because directory listings (Glama) build the server and probe it. Build and probe it the same way they do:

docker build -t laver-mcp .
printf '%s\n' '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"probe","version":"1"}}}' \
  '{"jsonrpc":"2.0","method":"notifications/initialized"}' \
  '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}' | docker run -i --rm laver-mcp

That must return all tools without LAVER_API_KEY set — the key is only needed once a tool actually calls the API. A server that refused to start without credentials would fail the listing checks.

Git rules

  • Commit only when explicitly asked, and stage only intended files.
  • No AI attribution anywhere in the repo's public record: no Co-Authored-By trailer naming an assistant, no "Generated with" footer in commit messages, PR titles or PR bodies, and no assistant named as an author. The commit is authored by the person who asked for it.
  • Naming Claude, Cursor or any other client in documentation is unrelated to the above and stays — this server supports them and the README says so.
  • Never amend, force-push or reset hard unless explicitly requested.

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.
