MCP Checkup MCP Server

About MCP Checkup

MCP Checkup checks public remote MCP servers on a schedule: whether they answer, which protocol revision they negotiate, and whether their tool list or schemas changed versus an approved baseline. Every result is an Ed25519-signed attestation anyone can verify against the published keys. It is also an MCP server itself (https://mcpcheckup.com/mcp, Streamable HTTP, no auth) with tools to look up reports, history and attestations, so agents can check a server before they use it. Official MCP Registry name: com.mcpcheckup/mcp. Tags: Monitoring, Developer tools, Security.
