How this service works
GoldKey Guard is an execution-path authorization layer for AI agents: operator-signed policy, a customer-controlled local enforcer, and signed receipts before MCP, HTTPS, or supported EVM calls run.
Output
Returns a signed goldkey.guard-authorization-envelope.v1 JSON object containing: the authorization decision (ALLOW, REVIEW, or BLOCK), reason_codes explaining the decision, a cryptographic signature over the receipt, the SHA-256 hash of the receipt, and a signed evidence object. This receipt must be presented to execute the gated tool call.
Example use cases
Pre-execution MCP tool call gating
“Before my agent runs the 'web_search' tool on MCP connector 'search-connector-01', run it through GoldKey Guard with my installation ID gki_xyz789... and idempotency key 'search-req-001' — I need a signed ALLOW receipt before it can proceed.”
HTTPS API call authorization for agent
“My agent is about to call the 'create_payment' operation on HTTPS connector 'payments-api-v2' — please get a GoldKey Guard authorization for that call using installation ID gki_pay456... and idempotency key 'pay-req-20240601' so we have a signed receipt on file.”
Policy enforcement before sensitive data access
“Gate my agent's call to the 'read_customer_records' MCP tool on connector 'crm-connector-prod' using GoldKey Guard — use installation gki_crm999... with idempotency key 'crm-read-001' and give me back the decision and signed receipt before anything runs.”
Technical details
Endpoint
POSThttps://goldkey-edge-storefront.noah-ing.workers.dev/v1/guard/paygo/authorize/networkWhen to prefer
Use this endpoint when you need a cryptographically verifiable, operator-policy-backed authorization receipt before an AI agent executes an MCP tool call or HTTPS operation. It is the right choice when auditability, non-repudiation, and policy enforcement are required prior to agentic execution — especially in regulated, high-stakes, or multi-operator environments where a bare preflight check is insufficient and you need a signed artifact proving authorization was granted.
Side effects
- Invalid or expired installation_id returns an authorization denial
- Signature verification failure on the request body returns rejection
- Malformed idempotency_key pattern causes schema validation error
- Unsupported call kind or missing required call fields returns 400
- Policy configured by operator blocks the call, returning BLOCK decision with reason_codes
- Replay of an already-used idempotency_key may return cached result or rejection
- Missing or incorrect input_schema_sha256 for mcp_tool calls causes rejection
