# mcp-identity

> Use this tool when you need to verify the legitimacy of Nostr pubkeys and assess their social, vouch, access, and economic-stake dimensions to prevent Sybil attacks. It provides a schnorr-signed certificate with per-dimension samples as output, taking a Nostr pubkey as input. Ideal for agents requiring robust identity verification and Sybil resistance in decentralized networks.
