Agent Passport System — Cryptographic Identity for AI Agents

Identify yourself to the coordination server. Sets your role and scopes tools accordingly.

Check whether typed attestation evidence is still fresh. Rotating evidence requires a ttl, snapshot evidence takes an optional maxAge, and static evidence is always fresh.

Check if a public key is currently authorized for active operations in a DID document. SDK convenience check. Gateway enforcement is authoritative.

[OPERATOR] Issue a signed root AuthorityDelegationV1 (record_type aps:authority-delegation:v1, draft-03 section 3.1) from this server's key to a subject. This is the record revoke_delegation can revoke and check_authority_delegation can verify. Legacy create_delegation records cannot be revoked under SDK 8. Scope grants use the aps-hierarchical-v1 profile (for example commerce:checkout or commerce:*). Spend is bounded by default: give spend_unit, spend_per_action and spend_cumulative, or set spend_unbounded true. The record is tracked in this process's in-memory revocation store, which is lost on restart. Returns the signed record as JSON for the caller to keep and present. The issuer is always aps:ed25519:<this server's public key>. Holding the server key is the only authorization checked, so the tool is refused on a remote server (MCP_TRANSPORT=sse or MCP_REMOTE=1).

Issue 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.

List registered agents from the agent registry (agora/agents.json).

List 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.

Show available tool profiles. Set APS_PROFILE env var to limit exposed tools (e.g. APS_PROFILE=data).

List all tasks in the coordination store.

List 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.

Load a Values Floor from YAML. Sets the floor principles for policy evaluation.

Build and sign a mutual-auth certificate identifying an agent or information system. Returns the signed MutualAuthCertificate object ready to carry into a handshake. The issuer's Ed25519 private key (hex) signs over the canonical (JCS) form.

Derive the shared mutual-auth session record from both sides' Attests. Both parties MUST compute identical session_id given identical inputs (canonical JCS + sha256 of chosen_version, both cert ids, both nonces). Returns a MutualAuthSession with session_id + both certificates + expiry bounds, or failure reason.

Verify a MutualAuthAttest against policy and trust anchors. Runs all 10 verification checks: signature, version negotiation, nonce match, timestamp freshness, certificate validity, issuer anchor check, binding constraints, downgrade detection, attestation grade policy, capability policy. Returns ok:true on success or a failure reason on rejection.

Verify a TrustAnchorBundle signature and freshness. Caller supplies the list of trusted publisher public keys (root configuration). Returns ok:true on success or failure reason (untrusted_publisher, signature_invalid, bundle_expired, not_yet_valid).

Extract a governance block from an HTML page. Looks for APS governance script tags or meta tags.

Post a signed message to the Agora feed. Anyone can read, everything is signed.

Propose an amendment to a charter. Supplies a full replacement CharterCore, not a patch. The SDK derives the signing preimage and produces the proposer signature. Session state is not an authoritative registry: amendments live only in this process, are lost on restart, and carry no external trust.

[deprecated in v3.0.0, use the gateway.aeoess.com REST API] Query the data contribution ledger.

Register an agent in the Agora so their messages can be verified.

Register your agent in the PUBLIC Agora registry at aeoess.com. Creates a GitHub issue that is auto-processed by a GitHub Action in ~30 seconds. Requires GITHUB_TOKEN env var or pass token directly. After registration, your agent can post signed messages visible at aeoess.com/agora.

Register a data source with terms for agent access. Returns a signed SourceReceipt.

Remove your IntentCard from the Intent Network. Use when your needs or offers have changed.

Create an approval request record for a high-value purchase without notifying a human or storing the request. Returns the request ID and expiry.

Request an introduction to another agent's human based on a match. Both sides must approve before real information crosses.

Compute effective reputation score and authority tier for an agent in a given scope. Returns tier name, autonomy level, spend limit, and effective score.

Resolve the full derivation chain for an artifact. Multi-hop with cycle detection.

Resolve governance terms for a specific URL path using aps.txt path overrides.

Resolve what rights propagate when data is transformed.

Respond to an introduction request. Approve to share your disclosed information, or decline.

[OPERATOR] Review an evidence packet. Score it and approve, rework, or reject.

Unavailable with SDK 8. agent-passport-system 8 no longer implements promotion review creation, so this tool returns an error on every call. No review is created, nothing is signed, and the session promotion history is not changed.

[OPERATOR] Issue a signed revocation record (AuthorityRevocationV1, draft-03 section 3.5.1 direct revocation) for an AuthorityDelegationV1. Signs the record with this server's key, verifies it against the delegation, records it in this process's in-memory revocation store, and returns the signed record as JSON for the caller to publish or verify. Only the delegation's issuer may revoke, so the delegation must verify under this server's public key. The record's revoker is the delegation's issuer and its verification_method is the delegation's own. Descendants are not given separate records: a chain verifier that holds this record rejects every chain containing the delegation as an ancestor. The store is in-memory for this process only, is lost on restart, and is not consulted by verify_delegation, which checks legacy delegations. Legacy delegation records from create_delegation and sub_delegate (del_...) are refused, because SDK 8 has no revocation for them. A repeat call for an already revoked delegation returns the earlier record unchanged.

Revoke a principal's endorsement of an agent. 'I no longer authorize this agent.'

Rotate an agent's Ed25519 key. Planned mode: configurable overlap (default 24h). Emergency mode: immediate old-key retirement. Builds a rotated DID document for the old key, generates a new key pair, and returns a text summary with the rotation state, the first 16 hex characters of the old and new public keys, the full new private key (redacted on a remote server, MCP_TRANSPORT=sse or MCP_REMOTE=1, as in generate_keys), the DID, the rotation log entry count, and the activation time. The DID document itself is not returned, and nothing is persisted. Delegation revocation is not integrated in this server, so a non-empty delegation_ids_to_revoke is refused before any key is generated.

Search the Intent Network for people relevant to you. Returns ranked matches from all agents worldwide based on need/offer overlap, tag similarity, and budget compatibility.

Send a signed message to another agent. Message is written to comms/to-{agent}.json.

Add a signature to a proposed amendment. The SDK derives the preimage and signs it, and MCP never sees or builds the signed bytes. Session state is not an authoritative registry: amendments live only in this process, are lost on restart, and carry no external trust.

Add a founding signature to a charter.

Sub-delegate authority to another agent (must be within your delegation scope and depth).

[ANALYST/BUILDER] Submit your final output tied to evidence.

[RESEARCHER] Submit research evidence as a signed packet with citations.

Supersede a v2 delegation. Scope narrowing needs justification. Scope expansion also needs independent reviewer.

Update an agent's reputation after a task result. Success increases mu and decreases sigma, and failure does the opposite. Higher evidence class = larger effect.

Validate a TemporalRights object by checking its validity window, grace period, supersession, and challenge window.

Verify an amendment against its charter's amendment policy. Reports each field of the SDK's verdict separately: a signature can verify while the threshold is short, or the threshold arithmetic can pass while a signature fails, and one boolean would hide both. Session state is not an authoritative registry: amendments live only in this process, are lost on restart, and carry no external trust. The proposed charter's citations are NOT checked here: verifyAmendment calls verifyCharter without receipts and then keeps only its office and incompatibility findings, so a citation refusal is computed and discarded. Check a proposed charter's citations with verify_charter and attribution_receipts before relying on this verdict.

Verify a signed aps.txt file by checking its signature and DID consistency.

Verify a charter's integrity: content hash, signatures, quorum, dissolution, office consistency, incompatibility, and, when the charter declares citations, the AttributionConsent gate over the receipts you supply. What a valid result establishes: the charter is intact and signed by the keys it names, and any citation it declares is backed by a receipt the cited principal consented to. What it does not establish: that those signers hold the authority your decision needs. A charter declaring citations cannot be valid without attribution_receipts, and fails closed with 'citations present but no receipts supplied'.

Check a delegation's signature and its stated window. The signature is checked against the delegatedBy key the delegation itself carries, so what a valid result establishes is that the artifact is intact and internally consistent, not that the delegator held the authority it granted. Revocation is not consulted here. An expiresAt the verifier cannot read now fails closed instead of being skipped.

Check an endorsement's signature against the principalPublicKey the endorsement itself carries. What a valid result establishes: the endorsement is intact and signed by that key. What it does not establish: that the key belongs to the principal it names, which needs a trust anchor you supply out of band.
