@followed by the MCP server name and your instructions, e.g., "@mfp-mcp-vercelwhat did I log for breakfast today?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
mfp-mcp-vercel
MyFitnessPal connector for Claude, running on Vercel. A thin wrapper around delize/myfitness-mcp (installed as a pinned dependency) that makes it work serverless:
Stateless OAuth (
stateless_oauth.py): client ids, auth codes and tokens are HMAC-signed payloads, so the connector stays authorized across restarts and redeploys.Stateless MCP transport (
app.py): fresh server task per request, JSON responses.Cookies from env: MyFitnessPal session cookies come from
MFP_COOKIES.
Environment variables
Variable | Required | Notes |
| yes | Passcode you type once when connecting Claude. Changing it revokes all tokens. |
| yes | Raw |
| no | Public base URL. Defaults to |
| no | Time zone for "today" in the diary. Default |
| no | Access token lifetime in seconds. Default 30 days. |
Env var changes need a redeploy to take effect.

Connect Claude
Settings, Connectors, Add custom connector, URL https://<project>.vercel.app/mcp.
Leave client id/secret empty and enter the passcode on the login page.
Refreshing cookies
MyFitnessPal sessions expire (about 30 days). When tools start returning auth
errors: log into myfitnesspal.com, copy the Cookie request header again,
update MFP_COOKIES, redeploy.
Updating upstream
Bump the commit hash of myfitnesspal-mcp-service in pyproject.toml. app.py
overrides MCP SDK internals, so keep mcp pinned and retest when bumping it.
