MCP Identity Overview

mcp-identity MCP server exposes three tools for working with PowForge's Depth-of-Identity Oracle and Nostr public keys. It looks up multi-dimensional DoI scores, creates unsigned vouch events, and verifies signed certificates locally with Schnorr signatures. Score lookups use the oracle's L402 payment flow, while certificate verification does not require network access. Reach for it when an agent or paid API needs identity-based scoring, vouch construction, or offline certificate checks.

Primary Use Cases for MCP Identity:
  • Score a Nostr pubkey before handling a paid API request
  • Build an unsigned vouch event for another Nostr identity
  • Verify a signed DoI certificate without network access
  • Use identity depth as a pricing or rate-limit input
