Cronometer MCP Server

An MCP (Model Context Protocol) server that provides access to your Cronometer nutrition data. Pull detailed food logs, daily macro/micro summaries, manage diary entries, fasting, biometrics, and recurring foods - all from Claude, Cursor, or any MCP-compatible client. Its 31 documented tools cover macro, food, diary, entry. It runs locally over stdio via the published package.

People connecting this server to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Cronometer

before you install - you'll need

Set CRONOMETER_USERNAME, CRONOMETER_PASSWORD, CRONOMETER_DATA_DIR before connecting.

Claude Code

claude mcp add cphoskins-cronometer-mcp -- uvx cronometer-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "cphoskins-cronometer-mcp": {
      "command": "uvx",
      "args": [
        "cronometer-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

pypi package cronometer-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.cphoskins is GitHub-verified and matches the repo owner

03 · What Cronometer can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can search the Cronometer food database, list this account's diary groups and the values diary_group accepts, get full nutrition info and serving measure IDs for a food, and add a food entry to the diary.

Capability map

Tools grouped from the project's README - what Cronometer lets an agent do.

read & search

5 tools - e.g. Daily macro totals (calories, protein, carbs, fat, fiber); Detailed vitamin/mineral breakdown with period averages; Search the Cronometer food database

get_daily_nutrition · get_micronutrients · search_foods · get_repeated_items · get_recent_biometrics

Macro

5 tools - e.g. Get daily macro targets (or full weekly schedule with target_date="all"); Update daily macro targets (partial updates supported); List all saved macro target templates

get_macro_targets · set_macro_targets · list_macro_templates · create_macro_template · set_weekly_macro_schedule

Food

4 tools - e.g. Individual food entries with macros + micros for a date range; Get full nutrition info and serving measure IDs for a food; Add a food entry to the diary

get_food_log · get_food_details · add_food_entry · remove_food_entry

Diary

2 tools - e.g. List this account's diary groups and the values diary_group accepts; a diary group name (case-insensitive) or a 0-based index.

Is Cronometer still maintained?

Yes - as of 2026-08-25, its last commit was 2026-08-20 and it shipped 4 releases in the last 90 days. We re-verify nightly.

What can Cronometer do?

How do I install Cronometer?

Run `uvx cronometer-mcp`. The README documents 3 environment variables (CRONOMETER_USERNAME, CRONOMETER_PASSWORD, CRONOMETER_DATA_DIR) to set first. Set CRONOMETER_USERNAME, CRONOMETER_PASSWORD, CRONOMETER_DATA_DIR before connecting. You can also paste the ready-made client config above.

Does Cronometer run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
