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 remote - your agent's requests go to mcp.spacefrontiers.org

endpoint auth requires authentication - rejected our unauthenticated MCP initialize

license MIT - declared in the repository

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