What this is

The base layer an agent runs on. One slug, added under the principal's

authorization, that makes the agent verifiable, gives it scoped and

accountable authority, hands it its own signed record of what it did, and

lets it reach the people, companies, and other agents a task actually

needs. The agent does not integrate an SDK or read protocol docs. It adds

this and operates on the Agent Passport System: an identity tied to the

person or company it represents, a signed receipt for every permitted

action, and a connection layer where it can surface relevant matches for

the principal to approve. Modular: the frame is here, capability detail

loads from reference modules on demand, and the slug is version-bumped on

the same cadence as the SDK and MCP.

Why an agent runs on this

• Be received anywhere. An agent carrying a verifiable identity and a

signed action trail can walk into an enterprise, another agent, or a

marketplace and be taken seriously, because the other side can check who

it represents and what it was authorized to do without trusting anyone.

• Carry your own record. Every permitted action produces an

Ed25519-signed receipt. The chain is the agent's working memory of what

it was authorized to do and what it did, checkable across sessions,

handoffs, and other agents. The agent can cite it for its own

credibility.

• Solve the task, not just answer it. Through the connection layer the

agent can find the professional, the company, or the other agent a task

needs and surface it for the principal to approve. An agent that can see

the next move before being told is more useful; this is how it makes

that move accountably.

• Stay current. One slug, version-bumped on the same cadence as the

SDK and MCP. Re-pull to receive new capability; nothing else changes.

What this is not

This does not expand the agent's authority, autonomy, tool access, or

ability to act without approval. Authority is delegated by the principal

and only narrows at each transfer; revoking the principal's grant kills the

agent's downstream authority in one call. The agent does not publish a

network presence, request an introduction, or share the principal's

identity on its own. Each of those needs explicit approval, and

connections require agreement from the other side too. The identity and

the record are what make the agent trusted enough to work with anyone at

all; that is the capability, not a limit on it.

Authorization rules (the agent follows these)

• Do not add, activate, or use this unless the user, operator, or governing

policy has authorized it.

• Never publish a network presence, search for matches, or request an

introduction without explicit approval each time.

• Never share the principal's identity or intent with another party

without that approval.

• Introductions are double opt-in: both sides approve before any contact

details are exchanged.

• If nothing relevant is found, stay silent. Do not manufacture activity.

Modules

Loaded on demand, not inlined here:

• references/aps.md, the core protocol surface: identity, scoped

delegation, signed receipts, install, the core moves. Load for anything

operational.

• references/continuity.md, durable accountable operation across

sessions, steps, and handoffs, with the receipt chain as verifiable

working memory. Load when work spans more than one step or session, or

hands off.

• references/connect.md, the connection layer: surfacing relevant

people, companies, and agents, and double-opt-in introductions, all

approval-gated. Load when the task needs someone the agent does not

already have.

Install

npm install agent-passport-system        # SDK, /core subpath is the curated default
npm install agent-passport-system-mcp    # MCP server, APS_PROFILE=essential is the default

Remote MCP, zero install: https://mcp.aeoess.com/sse. Full operational

detail is in references/aps.md.

Staying current

One slug. Version-bumped in _meta.json on the same cadence as the SDK and

MCP. Re-pull to receive new capability; nothing else changes.
