endpoint auth requires authentication - rejected our unauthenticated MCP initialize

license no standard license detected - usage rights unclear; check the repo before commercial use

npm package @tomba-io/tomba-mcp-server - published under the repo owner's npm scope (@tomba-io)

registry namespace io.github.tomba-io is GitHub-verified and matches the repo owner
