Cronometer

Overview

Cronometer is a Model Context Protocol server that connects AI assistants to your Cronometer account for food logging, macro tracking, fasting data, biometrics, and recurring foods. Any MCP-compatible AI can call Cronometer's tools directly, deciding when to use them during conversation or agent runs.

The server runs locally as a Python package installed via uvx cronometer-mcp, communicating over stdio on your machine. You'll need your Cronometer credentials: set CRONOMETER_USERNAME and CRONOMETER_PASSWORD as environment variables. Version v2.0.3 is available now under the MIT license, with full source code at cphoskins/cronometer-mcp on GitHub.

Cronometer is listed in the Development category and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and all other MCP clients. If you maintain this server, claim the listing to verify ownership and keep information up to date.
