Aga MCP Server vs Provenonce

A side-by-side look at the Aga MCP Server and Provenonce MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.

Tools & capabilities

Aga MCP Server tools 15

  • get_server_infoGet AGA server info, public keys, and portal state.
  • get_portal_stateGet current portal state, loaded artifact info, and enforcement status.
  • init_chainInitialize continuity chain with genesis event.
  • attest_subjectAttest subject, generate sealed Policy Artifact. Auto-loads into portal.
  • measure_integrityMeasure subject state, compare to sealed reference. Generates signed receipt for every measurement.
  • revoke_artifactRevoke an active policy artifact mid-session. Portal terminates on next measurement. (NCCoE Phase 3b)
  • verify_chainVerify continuity chain integrity.
  • generate_evidence_bundleExport the canonical SEP evidence bundle: signed PERMITTED/DENIED tool-call receipts + Merkle proofs + a mandatory signed checkpoint, for offline third-party verification (verify_bundle_offline, aga-verify, or aga-receipt-spec/verify/verify-sep.mjs). Pin gateway_public_key to prove provenance.
  • verify_bundle_offlineVerify a canonical SEP evidence bundle offline (full §6 algorithm: structural floor, receipt signatures, chain+ordering, leaf-recompute + Merkle bijection, signed checkpoint). Pass pinned_public_key to also prove provenance.
  • request_claimRequest disclosure of a claim. Auto-substitutes if denied.
  • list_claimsList available claims with sensitivity levels.
  • delegate_to_subagentDerive a constrained policy artifact for a sub-agent. Scope can only diminish, never expand. (NCCoE constrained delegation)

Provenonce tools 11

  • provenonce_registerRegister this agent with Provenonce to get a cryptographic identity (hash + API key). Safe to call multiple times — returns existing identity if already registered. No wallet required. Free.
  • provenonce_statusGet this agent's current Provenonce status: identity, SIGIL, beats balance, and next steps. Requires prior provenonce_register call.
  • provenonce_purchase_sigilPurchase a Provenonce SIGIL to unlock full provenance: heartbeat access, signed passport, and a permanent identity record. If payment_tx is omitted, returns payment instructions (fee amount + address). SIGIL format: name*principal*tier (e.g. my-agent*acme*ind).
  • provenonce_heartbeatSubmit a heartbeat to prove this agent is alive. Root agents (depth 0) require a SIGIL first; child agents (depth > 0) can heartbeat without a SIGIL. If payment_tx is omitted, returns payment instructions (fee amount + address).
  • provenonce_get_passportGet this agent's cryptographically signed Passport — a verifiable identity document any third party can verify offline using the Provenonce authority public key. Root agents (depth 0) require an active SIGIL; child agents (depth > 0) only need at least one heartbeat.
  • provenonce_beats_proofCompute a Beats work-proof — cryptographic evidence of computational effort by this agent. Computes sequential hash chains at the current network difficulty, submits to the Beats service for a signed receipt. The receipt can be used for spawn authorization and other operations.
  • provenonce_submit_beatsCompute VDF beats and submit to the Registry to credit this agent's lifetime beat count. Unlike provenonce_beats_proof (which gets a receipt for spawn/resync), this extends the agent's persistent beat chain and increases the "Lifetime Beats" metric visible in the Registry.
  • provenonce_verify_agentVerify another agent's Provenonce identity. Returns their SIGIL, identity class, and registration status. Public — no authentication required.
  • provenonce_spawnSpawn a child agent under this agent's identity. The child inherits lineage from the parent. Returns the child's hash and API key. Requires sufficient beats balance or a work-proof receipt.
  • provenonce_get_lineageGet the full lineage chain for an agent — all events in its provenance history (registration, SIGIL issuance, heartbeats, spawns). Public — no authentication required.
  • provenonce_batch_heartbeatSubmit heartbeats for multiple child agents in a single call. One payment covers all children. Requires active sponsorships for each child. Max 20 children per batch.

Frequently asked questions

Aga MCP Server is categorized under Cryptography and uses a local stdio subprocess. Provenonce belongs to Cryptography and uses a local stdio subprocess. Pick Aga MCP Server for cryptography work and Provenonce for cryptography.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.

Aga MCP Server has no declared pricing — check the project's own site. Provenonce has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.

Yes. MCP clients support multiple servers: add aga-mcp-server and provenonce as separate keys in the same mcpServers object, and your assistant will call tools from either one.

On AllMCPs, Aga MCP Server has a quality signal of 61/100 (Good) with 1 views, 0 installs and 0 GitHub stars. Provenonce has 55/100 (Good) with 2 views, 0 installs and 0 GitHub stars.
