FAQ
- What is an MCP server card?
- An MCP server card is public metadata that tells agents where a Model Context Protocol server lives and what safe tools or resources it is meant to expose.
- Does this checker connect to my MCP server?
- No. It looks for public discovery evidence such as well-known server-card locations and linked metadata. It does not call protected tools or require credentials.
- Should content-only sites publish an MCP server card?
- Only publish one when there are real capabilities to describe. A content site may be better served by readable HTML, sitemap.xml, /llms.txt, and accurate schema.
- What should the card clarify for agents?
- The card should make the server name, description, capability boundaries, authentication posture, and public-versus-gated actions clear enough to avoid guessing.
