Garmin enthusiasts and developers leveraging the Model Context Protocol (MCP) integration for Garmin devices have a new update to explore: mcp-garmin 0.3.0 is now live. This release packs meaningful improvements, bug fixes, and new capabilities designed to streamline how you connect Garmin wearables and fitness tools with MCP-powered workflows.
What is mcp-garmin?
If you’re new to this tool, mcp-garmin is an open-source server that bridges Garmin Connect data with the Model Context Protocol (MCP). MCP is a standardized framework for connecting AI systems and developer tools to external data sources securely.
It lets you pull your Garmin workout history, sleep stats, heart rate data, and more into MCP-compatible apps without manual CSV exports or complex API workarounds. The tool is maintained by Garmin’s developer ecosystem team and the open-source community.
Key Updates in mcp-garmin 0.3.0
The mcp-garmin 0.3.0 release focuses on expanding data access, fixing pain points, and improving performance for all users. Below are the most impactful changes.
New Health Data Endpoints
Three new data endpoints are now available in mcp-garmin 0.3.0: Body Battery trend tracking, daily stress level metrics, and menstrual cycle health data for compatible Garmin devices.
These join existing endpoints for activities, sleep, heart rate variability (HRV), step counts, and hydration tracking. This gives developers and power users far more flexibility when building custom MCP workflows.
Streamlined Authentication Flow
Garmin Connect authentication was a common pain point for first-time users of earlier mcp-garmin versions. The 0.3.0 release fixes this with an updated OAuth 2.0 flow.
You no longer need to manually generate API tokens in the Garmin Developer Portal for basic access. The new flow walks you through login directly in your browser, cutting setup time for new users by roughly 40%.
Critical Bug Fixes
Over 12 community-reported bugs were resolved in mcp-garmin 0.3.0. This includes fixes for corrupted GPX file exports, missing swim activity data, and intermittent errors when pulling multi-day sleep reports.
Users who previously had to manually re-sync Garmin data after failed pulls will notice far fewer interruptions with this update.
Performance Optimizations
Large data pulls, such as retrieving 1+ year of activity history, now run 30% faster thanks to optimized database queries in mcp-garmin 0.3.0.
The server also uses 20% less memory when running in background mode, making it more efficient for low-resource environments like Raspberry Pi or shared hosting.
How to Update to mcp-garmin 0.3.0
Updating to the latest version takes less than 5 minutes for most users. Follow the steps below based on your installation method.
- If you installed mcp-garmin via npm: open your terminal and run
npm update mcp-garmin - For Docker users: pull the latest image with
docker pull ghcr.io/garmin/mcp-garmin:0.3.0 - Restart your MCP server instance to apply all changes
- Verify the update by running
mcp-garmin --version— the output should display 0.3.0
Who Should Update Immediately?
While all users are encouraged to update, the following groups will see the biggest benefits from mcp-garmin 0.3.0:
- Users who previously experienced sync errors with swim activities or multi-day sleep reports
- Developers building MCP tools that need access to Body Battery or stress level data
- Anyone running mcp-garmin 0.2.x or earlier, as this release includes critical security patches
What’s Next for mcp-garmin?
The development team has shared a tentative roadmap for the next major release, mcp-garmin 0.4.0, targeted for Q4 2024.
Planned features include support for Garmin Coach training plans, real-time activity streaming during workouts, and expanded OAuth scope customization for enterprise users. You can track progress and submit feature requests on the official mcp-garmin GitHub repository.
Final Thoughts
The mcp-garmin 0.3.0 release is a meaningful step forward for anyone integrating Garmin data with MCP workflows. With new health endpoints, easier setup, and critical bug fixes, it’s a low-risk, high-reward update for all users.
Update today to take advantage of the improved performance and expanded data access — and keep an eye out for the 0.4.0 release later this year.
