When does this happen?

IF Using a standard Sentry auth token (with only org/ci scopes) to configure the Sentry MCP server in Claude/Cursor triggers a `'str' object has no attribute 'message'` error when fetching an issue.

How others solved it

THEN Instead of a standard token, create a custom internal integration in Sentry under Settings > Developer Settings > Internal Integration. Assign appropriate scopes (e.g., issues:read). Generate an auth token using the 'New Token' button on that integration page (not the Client Secret). Use this token in the MCP server configuration.
