FAQ from Devvit Mcp

How do I opt out of telemetry?

Set the DEVVIT_DISABLE_METRICS environment variable to "true" in the MCP server configuration. Example: "env": { "DEVVIT_DISABLE_METRICS": "true" }.

Why do I see “Unexpected token” errors when using console.log?

Avoid using console.log in the hot path of your app. The MCP protocol expects strict JSON output; console.log breaks that. Use the provided logger shim instead, which handles conversion automatically.

How can I debug the Devvit Mcp server during development?

Run npm run dev and list/trigger tools directly in your editor. For live testing with logs, use the Claude Desktop app; it writes error logs to your machine that you can view with tail or open in VSCode.

What does the error “Server does not support logging” mean?

The server lacks the logging capability required by some MCP clients. You must add the logging capability when initializing the MCP server. See the typescript-sdk reference for the exact key to include.

How is versioning handled?

Versioning is fully automated through CI/CD. The version in package.json is a placeholder; actual released versions are tracked via git tags only.
