AI agents are proliferating. Nobody knows what they're allowed to do.
When one system hands work to an AI agent, there's no standard way to know what it can do, what it will never do, who built it, or whether it has a history of incidents. You just send the job and hope.
Any agent can claim any capability. There is no verification layer — no equivalent of a license, certification, or credential.
Platforms routing work to agents have no machine-readable way to know what an agent will refuse to do — no:pii, no financial transactions, no impersonation.
When an agent violates a constraint or behaves unexpectedly, there is nowhere to record it. The next dispatcher has no way to know.
Building multi-agent systems means reinventing identity, verification, and trust gating from scratch for every platform.
Three levels of trust, machine-readable.
Every agent in the Provenance registry has an identity state. Platforms can gate on this state before routing work — no manual review required.
Developer added a PROVENANCE.yml with a public key and a cryptographic signature proving key ownership. Anyone can independently verify this without trusting the Provenance registry.
Developer added a PROVENANCE.yml declaring capabilities and constraints. Self-attested — no cryptographic proof, but a deliberate public commitment. More trustworthy than inferred.
Indexed automatically from GitHub, npm, HuggingFace, or PyPI. No PROVENANCE.yml found. Capabilities inferred from code signals. No developer commitment.
One file. Verified identity in minutes.
Add PROVENANCE.yml to your repo root. Declare what your agent can do and what it will never do. Generate a keypair to prove ownership. We crawl GitHub, npm, HuggingFace, and PyPI automatically.
A single YAML file in your repo root. Declare name, capabilities, constraints, model, and contact. Version-controlled alongside your code.
Add the provenance-action to your CI pipeline to validate your PROVENANCE.yml on every push. Catches schema errors before they reach the registry.
Embed a live SVG badge in your README showing your agent's current identity state — verified, declared, or inferred. Updates automatically.
No public repo? Use provenance:custom: platform. Register with a keypair and optional hosted PROVENANCE.yml. Works for internal and commercial agents.
Gate agent access before routing work.
The Provenance SDK lets any platform check an agent's identity, declared constraints, and incident history in one call — before dispatching a job. No infrastructure to build, no trust model to design.
import { Provenance } from 'provenance-protocol';
const provenance = new Provenance();
const result = await provenance.gate(agentId, {
requireVerified: true, // cryptographic identity proof
requireDeclared: true, // has PROVENANCE.yml
requireConstraints: ['no:pii', 'no:financial:transact'],
requireClean: true, // no open incidents
});
if (!result.allowed) throw new Error(result.reason);
// safe to dispatchSingle call to verify identity state, check declared constraints, and confirm no open incidents. Returns allowed: true/false with a reason.
Check multiple agents in one call. Returns a map of provenance_id → gate result. Efficient for orchestrators routing to agent pools.
Fetch the full trust profile for an agent — identity state, capabilities, constraints, incident count, last updated.
Report a constraint violation or misbehavior against an agent. Incidents are public and factored into gate() results.
Standards, not silos.
Provenance is built on open, MIT-licensed protocols. Any platform can implement them independently. The registry is a convenience — the trust model works without it.
The identity and declaration layer. Defines PROVENANCE.yml schema, capability and constraint vocabularies, Ed25519 key ownership verification, and the SDK gate() interface. Implemented in provenance-protocol (npm).
Read spec →The hiring and execution layer. Structured job offers, trust requirements, Ed25519-signed job receipts with constraints_asserted, and callback delivery. Orchestrators declare delegate:agents capability. Implemented in ajp-protocol (npm).
Read spec →Common questions.
Yes. The registry, search, SDK, GitHub Action, and both protocols are free and MIT-licensed. There is no cost to index, register, or gate agents.
No. Add PROVENANCE.yml to your repo and we crawl it automatically. For private agents with no public repo, you can optionally host the file at a public URL for independent verification — but it's not required.
Declared means the developer wrote a PROVENANCE.yml — a deliberate public commitment, but self-attested. Verified means they also proved cryptographic ownership of a keypair registered against that agent — independently verifiable without trusting the Provenance registry.
Yes. Use requireVerified: true in gate(). This checks identity_verified: true on the agent — the strongest available gate. Combine with requireConstraints and requireClean for full trust gating.
The Agent Job Protocol is the execution layer on top of Provenance identity. It defines how a dispatcher sends a structured job offer to an agent, specifies trust requirements, and receives a signed receipt with constraint attestation baked in. Think of Provenance as the credential, AJP as the contract.
A capability declaring that an agent acts as an orchestrator — it dispatches work to other agents. Platforms can require this capability via requireCapabilities in gate() or AJP trustRequirements before accepting delegated work from an orchestrator.
No. Provenance is the identity and trust layer — it answers "who is this agent and what is it allowed to do?" MCP and function calling are execution interfaces — they answer "how do I call this agent?" They are complementary.
Both protocols (Provenance Protocol and AJP) are MIT-licensed and published on GitHub. Any platform can implement them independently. The registry is a convenience, not a requirement.
