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.

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
