Is garmin-mcp-auth safe?
Garmin Connect sign-in for Garmin MCP, the unofficial MCP server for Garmin Connect: SSO, MFA, DI OAuth2 tokens and refresh. Not affiliated with Garmin.
This server can change things — files, a browser, a database, or paid online services. Limit what it can reach.
Why: writes or deletes files; controls a web browser.
What it can do
- Starts other programs
- Writes or deletes files
- Reads files
- Controls a web browser
- Calls internet services
How to use it safely
- ✓ It starts another program (often a browser for sign-in, or a bundled binary). Install it only from the official package.
- ✓ Point it at one project folder, never your home directory or a whole drive.
- ✓ Only give it the folders it needs; files it reads can end up in the AI’s context.
- ✓ Use a separate browser profile without your logged-in accounts.
- ✓ Content it fetches from the internet can carry prompt-injection instructions.
- ✓ Pin the version (below) so an update can't change what it does without you noticing.
Code patterns worth reviewing
Automated pattern matches in the published package. Some are expected for this kind of server, and some may be false positives — they are pointers for review, not confirmed vulnerabilities.
Command injection risk
The agent appears to pass input into a shell or command execution path.
