PEAC Protocol

Signed action records for AI agents, APIs, MCP tools, and gateways.

Automated systems already call APIs, run MCP tools, make gateway decisions, report payment events, and provision resources across system boundaries.

PEAC records those actions, decisions, and events as portable signed interaction records, so another party can verify what happened later without relying on screenshots, private logs, or unverifiable assertions.

Record locally. Verify across boundaries.

Start fast

Verify a sample offline: docs/guides/offline-sample-index.md
Compare verification paths: docs/guides/verification-options.md
Wire PEAC into MCP, OpenTelemetry, or a gateway: docs/guides/integration-patterns.md
Choose by role: docs/START_HERE.md

What PEAC records

PEAC is useful when a system does work and another party later needs to verify what happened without trusting that system's logs.

Event	Familiar surfaces	Example record
API call	Stripe-style APIs, Cloudflare Workers, Vercel functions, internal HTTP services	request, response, usage, access decision, policy-visible outcome
MCP tool run	MCP servers, Smithery-listed tools, internal MCP servers	tool input/output reference, tool result, issuer, timestamp, signature
Agent action	A2A handoffs, agent-framework steps, Microsoft AGT-style runtime events	action invoked, delegated, approved, denied, cancelled, or timed out
Gateway decision	Cloudflare, Portkey, Kong, API gateways, AI gateways	access, routing, export, or boundary decision reported by a gateway
Payment event	x402, paymentauth / MPP, ACP, AP2-style commerce flows	payment request, authorization, settlement observation, mandate, dispute context
Provisioning event	Stripe Projects-style provider setup, Vercel deployments, GitHub Actions, Terraform-managed resources	catalog, provider link, account, credential, budget, subscription, domain, deployment, or resource lifecycle event

These are orientation examples, not partnership claims or exclusive integration targets. PEAC records what those systems report; it does not replace them.

PEAC does not make those decisions. It records what another system reported, binds it to an issuer and time, and makes it portable for verification.
