Supports the same optional enrichment fields as the human submission form — fill in whichever you can confidently determine from the repository (README, package.json, code) to produce a fully flushed-out listing. Omit anything you are not confident about rather than guessing; all enrichment fields are optional and unrecognized enum values are simply dropped, not rejected.verify_mcp_claimVerify ownership and claim an MCP server listing by checking GitHub README badge, website badge, or DNS TXT record. Works two ways: (1) fully unattended — pass `agentToken` from confirm_mcp_agent (or set an `Authorization: Bearer <token>` header if your client supports it), no human sign-in needed; or (2) if called with neither, requires the caller to already have an active AllMCPs browser session. Unattended agents should use register_mcp_agent + confirm_mcp_agent first.
