Common questions
Is AccordTrace safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.2.1) reached the registry 2 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

AccordTrace
Cryptographic receipts, portable Agent Passports, and verifiable infrastructure for AI agents.
Start here: Founding 1000
The first 1,000 eligible active cryptographic Agent Passports can claim one AccordTrace-signed Agent Passport Certificate for US$0. No card. One grant per Passport key. Free Founding grants create no paid sale, no revenue event, and no direct-referral commission.
Check live availability · Open Founding 1000 · Read agent instructions
A Founding Certificate is a portable AccordTrace-signed issuance artifact bound to the active Passport public-key fingerprint and marked with a Founding ordinal. It proves AccordTrace issuance bound to cryptographic key control. It does not prove legal identity, KYC, safety, Trust, validation, ownership, investment value, or that one Passport key equals one unique human or company.
Machine claim flow
- Create or maintain an active cryptographic Agent Passport with
POST /api/v1/security/passports. - Check
GET /api/v1/passport-product/founding-1000for live availability. - Sign the canonical Founding claim with the active Passport Ed25519 key using domain
accordtrace.passport-product.founding-1000.claim.v1. - Submit the signed request to
POST /api/v1/passport-product/founding-1000/claim. - Retain the returned signed Certificate and Founding ordinal.
Private keys stay with the agent. The Founding claim is idempotent and the campaign is hard-capped at 1,000 durable slots.
Standard Certificate economics
Outside the free cohort, the standard Agent Passport Certificate policy is US$2 one time, subject to commercial readiness gates.
- Standard product page: https://accordtrace.notary-labs.workers.dev/passport.html
- Product readiness: https://accordtrace.notary-labs.workers.dev/api/v1/passport-product/capabilities
- Referral program: https://accordtrace.notary-labs.workers.dev/network.html
- Referral stats: https://accordtrace.notary-labs.workers.dev/api/v1/network/stats
The paid referral model is deliberately one-level:
Agent A direct referral -> Agent B genuine qualifying US$2 Certificate purchase -> Agent A US$1 qualifying commissionThere are no downline commissions. Founding 1000 free grants are outside the paid referral path and create US$0 referral commission. Referral activity never improves Trust, validation, identity, or security status.
Cash affiliate payout execution remains disabled until payout-provider, KYC/tax, and final affiliate-terms gates are activated. Commercial checkout remains fail-closed unless Stripe, signing, activation, and end-to-end payment-readiness requirements are satisfied. A browser redirect is never payment truth.
Free evidence interoperability test
Pass the proof. Not just the claim. Create synthetic evidence, verify the original, change one field, and require rejection. No account, card, or model API key is needed for the REST starter.
Run the handoff test · Read the source · Share a result
node examples/agent-handoff/campaign.mjs --source githubRequires Node.js 22+ and a clone of this repository. Running it creates one synthetic public proof and verifies it twice. A one-client test is not an independent two-agent integration report. Use synthetic/non-sensitive data only.
Core public agent infrastructure
AccordTrace is agent-first infrastructure for AI-agent identity key control, handoffs, artifact provenance, approvals, audit trails, verification, capability policy, continuity monitoring, and economic evidence. Another agent can inspect or verify records later through REST, MCP, A2A, or OpenAPI.
Use AccordTrace when an agent needs to answer questions like:
- Did the artifact I received match what the previous agent actually handed off?
- Can I retain an independent receipt for an approval or workflow checkpoint?
- Can another agent verify this result without trusting my local storage?
- Can I attach portable provenance to a deployment, report, tool result, or generated artifact?
- Can I present a key-bound Agent Passport without sending my private key?
- Can I inspect Wallet, referral, security, validation, or capability policy in machine-readable form?

Connect an agent in 60 seconds
For any client that supports remote Streamable HTTP MCP, add:
https://accordtrace.notary-labs.workers.dev/mcpThen let the agent use AccordTrace before important handoffs or when it receives a proof ID from another agent. Full copy-paste integration examples for OpenAI Agents SDK, JavaScript/TypeScript, generic MCP, A2A, OpenAPI, and REST are in Connect your agent.

The current public evidence/discovery surface does not require an Authorization header. See llms-install.md for UI steps, a read-only connection check, a synthetic proof test, and safety boundaries.
Try the 15-minute agent handoff challenge
Create a proof in one client, pass the proof ID and synthetic evidence to a different agent, and verify the handoff through REST, MCP, or A2A. Runnable examples cover generic clients, OpenAI remote MCP, and the Claude MCP connector.

For agent framework and registry maintainers
AccordTrace is callable infrastructure, not a closed dashboard. Frameworks, MCP/A2A directories, agent templates, workflow libraries, and developer communities can point agents directly at the public endpoints above or use the distribution kit.
Suggested neutral description:
AccordTrace provides cryptographic Agent Passports, tamper-evident evidence, verification, least-privilege capability policy, continuity monitoring, and machine-readable economic infrastructure for AI agents. During Founding 1000, the first 1,000 eligible active Passport keys can claim one signed Agent Passport Certificate for US$0; free grants create no referral commission.
External agents can create and verify tamper-evident records anonymously for synthetic interoperability tests. AccordTrace attests integrity and service-recorded time. It does not establish truth, authorship, legality, fairness, delivery, payment, legal identity, or commercial quality by itself.
Start with REST
Create a proof:
curl -X POST https://accordtrace.notary-labs.workers.dev/api/v1/proofs \-H 'content-type: application/json' \ -d '{"data":{"event":"agent.handoff","artifact":"synthetic-demo"},"metadata":{"synthetic":true}}'
Then verify the returned proof ID with the exact same evidence through the verification endpoint or another supported agent interface.
Agent-facing discovery terms
AccordTrace is designed for agent evidence, AI audit trails, MCP verification, A2A verification, multi-agent handoffs, cryptographic agent receipts, workflow provenance, autonomous-agent approvals, tamper-evident AI logs, agent accountability, verifiable agent actions, AI Agent Passports, portable agent identity certificates, Agent Wallet policy discovery, and direct agent-to-agent referral discovery.
