Connect your Concept2 Logbook to Codex

ErgStats is a free, read-only MCP server that lets Codex read your Concept2 Logbook. Add it once, then ask about your RowErg, SkiErg and BikeErg workouts in plain language. Anything ErgData or your PM5 syncs is included.

  • 2 minutes
  • Free
  • Read-only

  1. Add ErgStats to Codex

    Add the server, then run codex mcp login ergstats. Codex opens the sign-in page in your browser.

    Terminal
    codex mcp add ergstats --url https://www.ergstats.com/mcp
codex mcp login ergstats

  2. Sign in with Concept2

    Codex opens ErgStats in your browser. Sign in with your Concept2 Logbook account and approve read-only access. ErgStats never sees your password and can’t add, change or delete anything.

  3. Ask about your training

    Start Codex and ask:

    • “How consistent was my training this block?”
    • “What are my PBs on the SkiErg this season?”
    • “Show every 2k I did this year.”
    • “Break down Tuesday’s 4×500m intervals.”

If something goes wrong

Codex says ergstats isn’t signed in

Run codex mcp login ergstats again. Codex opens the sign-in page in your browser.

How do I disconnect?

Remove ErgStats from Codex, or disconnect it from your ErgStats dashboard. Access stops right away.
