MCP server for your Cronometer account: the full diary over Cronometer's mobile API, honest coverage-aware nutrition (missing is never zero), safe writes, and an optional OAuth remote connector.
Inferred from the transports this listing declares (stdio). A client not listed here hasn’t been ruled out — it just isn’t something Forge can confirm.
CRONOMETER_PASSWORDAPI keyoptionalCronometer password. Optional if setup saved it to the OS keyring.
CRONOMETER_TOTP_SECRETAPI keyoptionalBase32 authenticator key, for accounts with two-factor sign-in.
Declared by the author in the official MCP registry. Forge does not store, broker, or ever see these values — the config below is scaffolded with placeholders you fill in locally.
Verification confirms publisher identity (repo ownership), not code safety. The security scan covers known CVEs and suspicious install scripts.
Read out of the source npm actually ships, at scan time. The package was never executed. Tools registered dynamically at runtime, or hidden inside bundled or minified code, can be missed — so this is a floor on the tool surface, not a complete census of it.
statusReport whether live access, credentials and a cached session are configured, and the diary timezone. Never signs in or contacts Cronometer.Report whether live access, credentials and a cached session are configured, and the diary timezone. Never signs in or contacts Cronometer.

Tool names and descriptions are written by the publisher and shown verbatim as inert text. They are the strings an MCP client passes to a model, so Forge scans them for prompt-injection patterns — any finding appears with the security scan above. “Privileged” is a keyword match on the tool name, not an audit of what the tool does: a benign-sounding name can still do anything.
