Mcpcheck tools (2)

write = sends, deletes, buys or posts
  • check_mcp_trustFree

    Check if an MCP server is safe to install: returns a trust score (0-100, grade A-F). Accepts a registry name (io.github.x/y), a GitHub repo (owner/repo), or a remote MCP URL. For remote servers it live-connects and analyzes the actual exposed tools for tool-poisoning + capabilities, and checks the backing repo (maintenance, license, security policy, auth). Call BEFORE installing or recommending any MCP server.

  • scan_mcp_serverFree

    Scan and inspect an MCP server for security issues before connecting it: live tool-poisoning analysis, exposed-tool inventory + capabilities, TLS, and repo trust signals. Same engine as check_mcp_trust. Accepts a registry name, GitHub repo, or remote MCP URL.
