nakama-mcp AGENTS.md

nakama-mcp AGENTS.md is an instructions file for Codex, OpenCode from mlger/nakama-mcp. It costs 1,580 tokens per session, scanned A, original, Apache-2.0.

A repository instruction document for an MCP server, a program that exposes a running Heroic Labs Nakama game server to AI assistants. It explains the APIs, tools, directories, commands, and architecture rules.

In plain words
What is it for?
Use it when changing, testing, regenerating catalogs, or bundling this TypeScript Nakama integration.
Why use it?
It gives coding agents the project context needed to work safely with Nakama's player and administration interfaces.

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

nakama-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 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 is

An MCP (Model Context Protocol) server that exposes a running Heroic Labs Nakama instance to MCP hosts. TypeScript, ESM, strict mode. No runtime framework beyond @modelcontextprotocol/sdk + zod; HTTP transport uses bare node:http. Wraps Nakama's two HTTP APIs:

  • Client API (:7350) — player-facing (auth, accounts, storage, leaderboards, RPCs).
  • Console API (:7351) — admin/ops (search players, storage, status, ban).

Speaks stdio by default, or streamable-HTTP when MCP_TRANSPORT=http. Nakama exposes ~180 operations, so the server uses a search + execute design (nakama_search_actionsnakama_execute_action) over a generated catalog, plus ~12 promoted convenience tools.

Key directories

  • src/ — TypeScript source (see layer map below).
  • data/catalog.jsongenerated & committed, shipped in the npm package. Do not hand-edit; run npm run regen-catalog.
  • scripts/ — catalog regen (regen-catalog.mjs, lib/resolve.mjs) and MCPB bundling (build-mcpb.mjs).
  • test/ — each test is a standalone Node script (no test framework); see commands below.
  • docs/superpowers/ — design/plan notes for past features.

Commands

npm install
npm run build              # tsc -> dist/ (strict). ALWAYS build before testing — tests load dist/.
npm run dev                # tsc --watch
npm test                   # fast suite, no server (resolve + redact + smoke + http + http-reaper + version)
npm run test:integration   # needs `docker compose up -d --wait` first (stdio, Nakama 3.37.0 + CockroachDB)
npm run test:http-integration  # same prerequisite; drives the live server over the HTTP transport
npm run regen-catalog      # rebuild data/catalog.json from Nakama upstream (needs network)
npm run regen-catalog -- v3.37.0   # ...from a specific git ref/tag
npm run mcpb               # build + pack desktop bundle -> dist-mcpb/nakama-mcp.mcpb

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.
