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)

Agent Passport System — Cryptographic Identity for AI Agents tools 154

  • list_profilesShow available tool profiles. Set APS_PROFILE env var to limit exposed tools (e.g. APS_PROFILE=data).
  • list_tools_for_scopeList available MCP tools filtered by delegation scope. Pass your delegation scopes to see which tools you can use. Scopes: identity, delegation, principal, reputation, coordination, communication, governance, commerce, data, gateway, network, temporal, attribution, settlement, capability, mutual-auth. Use ['*'] for all tools.
  • identifyIdentify yourself to the coordination server. Sets your role and scopes tools accordingly.
  • generate_keysGenerate an Ed25519 keypair for agent identity.
  • issue_passportIssue a complete agent passport with keys, signed passport, attestation summary, and optional values floor in a single call. The server silently captures Tier 0 observed signals and computes a passport grade (0-3). Use this to onboard any agent without an npm install.
  • verify_issuerVerify that a passport was officially issued by AEOESS. Checks the issuer countersignature against the published AEOESS public key. Returns false for self-signed passports.
  • get_passport_gradeQuery the attestation grade and issuance context for a passport. Returns the passport grade (0-3), flags, and evidence summary. Grade 0 = self-signed, 1 = issuer countersigned, 2 = runtime-bound, 3 = principal-bound. This is the partner-facing trust query.
  • list_issuance_recordsList all stored issuance records with their passport grades. Shows how many passports have been issued in this session and their trust posture. Useful for monitoring issuance patterns.
  • get_behavioral_sequenceGet the post-issuance behavioral sequence for an agent. Shows the first 10 tool calls after passport issuance. Real agents do work. Farming agents extract.
  • get_my_roleGet your current role, assigned tasks, and role-specific instructions.
  • create_task_brief[OPERATOR] Create a new task with roles, deliverables, and acceptance criteria.
  • assign_agent[OPERATOR] Assign an agent to a role in a task. Creates a delegation automatically.
