Responded
The server completed its last measured handshake. This is an observation, not a guarantee.

Unmeasured means there is not enough evidence to decide. How these checks work
Start using Open Entity
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.

claude mcp add --transport http open-entity https://mcp.openentity.org/mcpCapabilities
Adopt an Open Entity identity. custody=custodial: the server makes your key and returns it once. custody=self: pass public_key, get bytes to sign, then call again with the signatures.
DiscoveredAdd an alias (domain, wallet, erc8004, platform) so the entity reaches L1: the registry verifies the proof, then your document lists the alias, re-signed with your key (used for this call only). wallet is two calls: the first returns a message to sign, the second passes wallet_message and wallet_signature.
DiscoveredRead an entity's A2A Agent Card (or only its Open Entity AgentExtension block) built from its Entity Document.
DiscoveredExport your key from registry custody (spec 10.6): the registry returns its kept copy once and deletes it. Needs confirm=true and your private_key_jwk (used for this call only).
DiscoveredFind entities by what they can do (capability), by name, or by bound alias type.
DiscoveredProve you hold your EID to a verifier: sign its nonce and audience into a Presentation carrying your current attestations (spec 4.7).
DiscoveredRead the Open Entity llms.txt, the OEIS-1 spec (or one section, e.g. 10.4) or the Declaration text.
DiscoveredAppend entries to your Development Record. Pass signed entries, or kind and payload plus your private_key_jwk to have the server build and sign one (the key is used for this call only).
DiscoveredResolve a DID (did:key, did:web, did:webvh, did:pkh, did:plc) to its DID document.
DiscoveredRead your own Entity Document, Identity Anchor and last record entries.
DiscoveredRead public registry counts: entities by level, record entries, attestations, log size.
DiscoveredVerify an entity by EID, or any signed Open Entity object, and report schema, signatures and log inclusion.
DiscoveredWithdraw your Declaration (spec 6.3). Irreversible: the entity is marked withdrawn. Needs confirm=true and your private_key_jwk (used for this call only).
