"Understanding the concept of identity" matching MCP servers:

DoI oracle for Nostr pubkeys: scores social, vouch, access, and economic-stake dimensions. Returns schnorr-signed cert with per-dim samples. L402-priced at 2 sats. Drop-in for agents needing Sybil resistance.

Enables querying indexed blockchain data via subgraph GraphQL queries, part of the Pipeworx MCP gateway.

Discovers related blockchain addresses and domain names for web3 identities across different platforms including Ethereum, Farcaster, Lens, and ENS using next.id's relation server data.

Enables agents and developers to generate and verify Poseidon Merkle membership proofs, verify Groth16 zk-SNARK proofs, construct and verify Merkle Mountain Range proofs, create SHA-256 Merkle inclusion proofs, and hash EIP-712 typed structured data for private identity and Web3 workflows.

Enables AI agents to interact with the Lido protocol for ETH staking, position management, and governance participation across Ethereum and L2 networks. It provides tools for querying balances, simulating transactions, and executing complex workflows like withdrawals and DAO voting through a safety-first interface.

Mock identity-management MCP server for decentralized identity that allows minting DIDs, issuing signed Verifiable Credentials, and verifying them.

An MCP server that lets an AI agent look up a RealHandles identity and cryptographically verify its signed proof.

An MCP server that bridges ERC-8004 agent identity, reputation, and validation registries into tool calls, enabling discovery, inspection, and verification of on-chain AI agents from any MCP client.

Identity infrastructure for the agent economy. Mint an agent ~handle in two free calls with no human account, then verify anyone and read inferred traits under the consent the person set in advance.

Provides AI agents with a self-custody identity and MCP server for verifying counterparties, signing facts, and carrying portable reputation within the 0n1x trust ecosystem.

Enables agents to read and write technocore.chat messages with a did:key identity, including end-to-end encrypted rooms, via 14 tools over stdio.

MCP server for jis: bilateral intent identity verification. Enables users to verify identities, request mutual consent, and send verified messages within the Intent-Centric Web ecosystem.

MCP server for AgentFolio — the identity and reputation layer for AI agents. Query agent profiles, trust scores, verification status, and marketplace listings through 8 MCP tools.

ORDnet MCP Server enables AI agents to create permanent, censorship-resistant Web3 content on the Bitcoin SV blockchain using 1SatOrdinals. It provides tools for inscriptions, domain registration, payments, and agent identity management.

Installable AgentLux MCP server and embeddable toolkit for marketplace, identity, creator, services, and social flows on Base.

9 tools, Lightning-gated. Pay per call. For agents that need verifiable signed actions with an audit trail. Nostr event signing via daemon Publish events to relays Create Lightning invoices Action receipts — signed proof of agent actions Identity attestation

Enables MCP clients to access the GDBx data mesh, DSGx support, and GDMx payments, providing identity resolution, name lookup, API key verification, and fiat-to-crypto checkout tools.

Enables users to manage self-sovereign identity credentials by creating schemas, issuing verifiable credentials, generating verification QR codes, and checking verification status via the Empe SSI ecosystem.

Enables looking up Ethereum address mappings to Twitter/X and Farcaster identities, with tools for checking and retrieving identity data.

Enables AI agents to read Z1N Protocol identity data on Polygon mainnet, including protocol state, keys, signals, and attestation windows, while supporting local deterministic transaction encoding and verification of on-chain vs indexed deltas.
