COROS Officially Overtakes Garmin
COROS just opened write access to its MCP. Build custom training plans with Claude or ChatGPT, no developer credentials needed.

I've been waiting for this day, and it finally happened.
COROS just released write access to its MCP. You can now create custom training plans with Claude and ChatGPT using natural language, without needing any developer credentials.
Why it matters
Until now, AI could read your watch data. Now it can write workouts and plans back to your watch. That's the piece Garmin still doesn't offer.
The guide
I created a setup guide and revamped the Strava MCP prompts to be COROS-specific.
Would this make you switch from Garmin?
