IntentFence

IntentFence is an open spend and action policy gate for autonomous AI. Put it immediately before a tool call, evaluate declared scope, cost, data-retention, and approval constraints, and run the downstream action only when the decision allows it:

safe_to_proceed
needs_review
denied

Production: https://agentpass-protocol.rmalka06.chatgpt.site

Protocol surfaces

Surface	Endpoint
Free REST preview	`POST /api/preflight`
Paid x402 decision	`POST /api/preflight/verified`
Receipt verification	`POST /api/receipts/verify`
Public ES256 keys	`GET /.well-known/jwks.json`
MCP Streamable HTTP	`/mcp`
A2A Agent Card	`GET /.well-known/agent-card.json`
OpenAPI	`GET /openapi.json`

The paid endpoint costs 0.05 USDC on Base through x402. A successful call returns both the facilitator's PAYMENT-RESPONSE settlement header and an IntentFence ES256 compact-JWS receipt.

For teams that need a guarded production workflow, the launch pilot is $750 plus $149/month and includes hands-on integration of one agent action. The Production plan starts at $499/month.

Important trust boundary

IntentFence 0.5 attests that it evaluated the inputs supplied by the caller. It does not independently prove real-world identity, authorization, or downstream enforcement. The receipt-signing key is separate from the USDC recipient wallet. IntentFence never needs a payer's seed phrase or wallet private key.

Local development

npm install
npm run dev

The production signing key is stored in Sites as the secret INTENTFENCE_SIGNING_PRIVATE_JWK. Generate a separate development key with:

node scripts/generate-signing-key.mjs /secure/path/intentfence-private-jwk.json

Never commit the generated private JWK. Publish only its public coordinates in /.well-known/jwks.json.

Validation

npm run test
npm run lint
npx tsc --noEmit
npm run sdk:check
npm run smoke:protocol -- http://localhost:3000

Set INTENTFENCE_TEST_PRIVATE_JWK_PATH only for a local smoke test that should exercise the signed-receipt verifier.

Distribution

TypeScript and Python SDKs live in sdk/. The root server.json is ready for the official MCP Registry under io.github.razel369/intentfence; the public MCP endpoint uses Streamable HTTP and requires no API key.

Commercial pilot

The fastest path to production is one guarded action: purchase, transfer, booking, deployment, deletion, or another consequential tool call. Submit the pilot form on the production site with the real action and its policy boundary.

See docs/PROTOCOL.md and docs/SECURITY.md for the protocol and security model.
