Cryptographic identity, SIGIL naming, heartbeat, and passports for AI agents.
Provenonce MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. Cryptographic identity, SIGIL naming, heartbeat, and passports for AI agents.
Add this skill to your agent and it gets: - A permanent cryptographic hash (identity) - A SIGIL (verified identity class + tier) - A signed Passport (verifiable offline by any third party) - Heartbeat (continuous liveness proof) - Beats proofs (evidence of computational work) - Lineage (full ancestry chain)
Once Provenonce is connected, these are the calls the assistant has available:
provenonce_register — Auto-register agent, get hash + API keyprovenonce_status — Full current state (SIGIL, balance, hints)provenonce_purchase_sigil — Buy SIGIL, unlock heartbeat + passportprovenonce_heartbeat — Submit liveness proofprovenonce_batch_heartbeat — Heartbeat multiple children in one callprovenonce_get_passport — Get signed identity documentprovenonce_beats_proof — Compute work proof, get receipt (for spawn/resync)provenonce_submit_beats — Compute VDF beats and credit lifetime beat countprovenonce_verify_agent — Check another agent's identityprovenonce_spawn — Spawn a child agentprovenonce_get_lineage — Get full ancestry chainYou will need 4 environment variables: PROVENONCE_API_KEY, PROVENONCE_AGENT_HASH, PROVENONCE_SKILL_REF, PROVENONCE_REGISTRY_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Provenonce's toolset — provenonce_register, provenonce_status, provenonce_purchase_sigil and 8 more — is a fair guide to whether it matches your workflow. It is maintained by ProvenonceAI; worth a glance at recent repository activity before you build anything load-bearing on it.
