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 · container (OCI image) - can be sandboxed away from your filesystem · remote - your agent's requests go to api.dc.library.northwestern.edu

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 @nulib/dc-api-mcp - published under the repo owner's npm scope (@nulib)

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