nutrition-mcp: Instructions file for Claude Code

CLAUDE.md

nutrition-mcp CLAUDE.md is an instructions file for Claude Code from RootMePLS/nutrition-mcp. It costs 5,249 tokens per session, scanned A, original, MIT.

A set of instructions for developers working on nutrition-mcp, a nutrition-focused tool server built with Bun and TypeScript. It documents the project, local database, running commands, deployment notes, publishing steps, and version-update locations.

In plain words
What is it for?
Use it when developing, running, restarting, migrating, publishing, or updating the nutrition-mcp project and its local PostgreSQL database.
Why use it?
It gives contributors one place to find the repository's development and release rules, reducing mistakes when running the server or changing its version.

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions subagents; names the TodoWrite tool.

This is RootMePLS/nutrition-mcp's own configuration. It tells Claude Code how to work on nutrition-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 nutrition-mcp configures →

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

nutrition-mcp CLAUDE.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.

Project Overview

nutrition-mcp is a Model Context Protocol (MCP) server for nutrition-related functionality, built with Bun and TypeScript. Entry point is src/index.ts. Server version must be updated in three places: package.json, src/mcp.ts (McpServer constructor), and server.json. The server icon is at public/favicon.ico. Tool call analytics (duration, success/failure, error category) are tracked via src/analytics.ts and persisted to the tool_analytics table in the local PostgreSQL database.

Running / deploying

The runtime server runs locally on this machine — there is no second server, no DigitalOcean, and no auto-deploy. bun run src/index.ts serves http://localhost:8080/mcp against the local PostgreSQL database nutrition_mcp (postgres://localhost:5432/nutrition_mcp). Merging to main only updates the source repository on GitHub; nothing ships anywhere. To apply a source change, restart the local server (bun --watch src/index.ts restarts automatically). Apply schema changes locally with psql per the README "Self-hosting" migration list. Registry/npm publishing (next section) is discovery metadata only and never deploys or affects the running server.

Publishing to the registry

Legacy tail from the original hosted project, and rarely required — publishing only refreshes MCP Registry discovery metadata and has no effect on the locally-running server. The MCP Registry is only discovery metadata pointing at https://nutrition-mcp.com/mcp, so a fix takes effect without republishing. To refresh the registry listing on a release, bump the version in all three places above, merge to main, then push a matching v* tag:

git tag v1.13.3 && git push origin v1.13.3

The .github/workflows/publish-mcp.yml workflow then runs the tests, verifies the tag matches server.json's version, and publishes via mcp-publisher using GitHub OIDC (no secrets). Each published version must be unique and is immutable once published, so always tag a fresh version — never re-tag an already-published one.

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.
