withings-mcp: Instructions file for Codex

AGENTS.md

withings-mcp AGENTS.md is an instructions file for Codex, OpenCode from davidmosiah/withings-mcp. It costs 158 tokens per session, scanned A, a copy of google-health-mcp AGENTS.md, MIT.

Repository instructions for an unofficial Withings connector, which connects agents to personal health, sleep, body-measurement, and activity data. They describe development commands and privacy rules for sensitive health information.

In plain words
What is it for?
Use them when developing or testing the Withings connector, checking its connection and privacy surfaces, or handling health data without committing secrets or raw personal records.
Why use it?
They make testing and building the connector more predictable while reducing the chance of exposing OAuth credentials or personal data. They also keep read-only summaries as the default behavior.

Instructions file for CodexOpenCode

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

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

withings-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.

Origin

This is a copy

86% identical to google-health-mcp AGENTS.md — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Agent Development Notes

Scope

This repo is the unofficial Withings MCP connector for local health, sleep, body and activity agents.

Commands

  • Install: npm ci
  • Typecheck: npm run typecheck
  • Build: npm run build
  • Fast smoke: npm run smoke
  • HTTP smoke: npm run smoke:http
  • Full gate: npm test

Rules

  • Never commit OAuth client secrets, access tokens, refresh tokens, personal Withings data, or local config.
  • Keep read-only behavior and privacy-safe summaries as the default.
  • Preserve agent-ready surfaces: manifest, connection status, privacy audit, CLI UX, Hermes agent manifest, and metadata checks.
  • Treat body measures and sleep data as sensitive health data.
Changes

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.
