Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · remote - your agent's requests go to opendata.cat

endpoint auth accepted our unauthenticated MCP initialize - no credentials needed to connect

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

npm package @opendata.cat/mcp-server - the @opendata.cat scope differs from the repo owner (xaviviro); confirm it's the project's official package

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