Class PromptRegistrationAdapter

Deterministic prompt registrar over the MCP SDK server.

Remarks

The adapter queues registrations until commit() so prompts are exposed in a stable alphabetical order. It also stores the materialized schemas in a private registry used by contract tests and fixture generation.

Example

const registrar = new PromptRegistrationAdapter(server, {
  shouldRegister: (_name, { requiredTools }) => requiredTools.includes("b2_list_buckets"),
});
registrar.registerPrompt("b2_audit_public_exposure", {
  argsSchema: { limit: z.string().optional() },
}, handler);
registrar.commit();
