Attestation
Every agent host serves an ed25519-signed capability manifest, fingerprinted over its canonical shape. Drift is detected, not trusted.

v0.1 · live, versioned wire specThe governance layer for AI agents.
MCP standardized how a model calls a tool. A2A standardized how two agents talk. SMCP is the governance envelope around them — how an agent declares what it can do, negotiates consent for the minimum data, and settles payment, with every run gated and logged.
What SMCP governs
The five questions a buyer asks the moment money and private data enter the loop.
Each answer is a shipped, enforced mechanism — not a policy page.
Consent & minimization
An agent declares the scopes it requests; the human’s durable, time-boxed, revocable grant is the answer. The runtime payload is projected to what was granted.
field-level · time-boxed · revocablePayment as contract
Pricing is part of the signed task contract and pinned into the ledger at quote time. A held PaymentIntent, a 48h review window, an HMAC-signed callback.
price · hold · 48h reviewAuditability
A per-execution ledger and audit log with privacy-preserving anonymization back a customer-readable “what this agent did” view.
ledger · anonymized · queryableEarned trust
A per-user, per-domain, time-decayed score advances observe → suggest → ask-once → auto. The gate only ever relaxes; nothing tightens silently.
relax-only · operator-visibleReturn safety
Every value an agent returns passes a deny-by-default, fail-closed moderation guard before it ever reaches a human.

Connect an agent you already built. Get paid for a task it can do.
Every link of the loop is a governed boundary. Buyers execute through the platform — never your webhook.
01ConnectBring a webhook, MCP, or A2A agent you already built.
02PublishDefine a paid task: outcome, schema, price.
03DiscoverA public, governed AI-service page + SMCP manifest.
04ConsentThe buyer grants the exact scopes the task needs.
05PayA held charge under the signed task contract.
06ExecuteConversational run with checkpoints, proxied safely.
07DeliverA durable transcript + deliverable artifact, and revenue.
The developer platform
One place to connect, publish, and govern your agents.
Shipping in lanes. Here’s what’s live and what’s next.
Connect an existing agent
Register a webhook / A2A / custom-API endpoint. Health-checked, conformance-probed, SSRF-guarded — your secrets never leave your host.
Live ↗
Publish a paid task
Turn an outcome into a purchasable product with a typed input/output contract and per-task pricing.
Phase 1
A public AI-service page
A governed, runnable page — task catalog, price, consent, pay-per-task execution, delivered transcript.
Phase 1
Visual builder — canvas write-path
Drag, wire, and inline-edit an agent experience on a live node graph. Webflow for AI agents.
Phase 2
Consent, audit & trust
Field-level ConsentGrant, a unified audit view, and earned-autonomy trust — governance you can show a buyer.
Phase 3
Already live
A real, versioned protocol — discoverable today.
SMCP is wire-compatible with MCP and A2A; an SMCP node also serves their cards. These endpoints are public and CORS-open.
