Keel.Endpoints.Idempotency

Safe retries for POST and PATCH. A client sends Idempotency-Key: <uuid>; the first request runs and its response is stored; a retry with the same key gets that response back (with Idempotent-Replayed: true) without running the handler again. No double charges when the network drops the first response.

builder.Services.AddKeelIdempotency();                 // IDistributedCache: memory, or Redis if registered

[Post("payments")]
public sealed class Endpoint(Payments payments) : ResultEndpoint<CreatePayment, Created<Payment>>
{
    public override void Configure(EndpointOptions options) => options.Idempotent();
    // ...
}

// or for every POST and PATCH under a group:
app.MapKeelEndpoints("/api").WithIdempotency();
Case Answer
New key Runs the handler; stores the response (unless 5xx) for 24 hours
Same key, same request The stored response, Idempotent-Replayed: true
Same key, different request 422 problem details
Same key while the first is running 409 problem details, Retry-After: 1
No key Runs normally; 400 with options.Idempotent(o => o.RequireKey = true)

Keys are scoped to the endpoint and the authenticated user. See the idempotency guide.

Keel.Endpoints.Agents

Safe actions for AI agents on Keel.Endpoints MCP tools: the server asks the user to confirm before a destructive or sensitive tool runs (MCP elicitation, stateless), with a signed confirmation bound to the tool, its arguments and the user, and an audit trail of every write an agent makes. Fail-closed: no confirmation, no action.
