The two tools are cleanly complementary: stamp_memory creates a receipt, verify_receipt checks one. There is no overlap and the descriptions make the create/verify split explicit.

Both names follow a strict verb_noun snake_case pattern (stamp_memory, verify_receipt). The convention is predictable and directly reflects each tool's action and target.

Two tools is thin in absolute terms, but the server's scope is deliberately narrow — stamp a memory and verify a receipt — and each tool clearly earns its place. Nothing superfluous is present.

The basic stamp/verify lifecycle is covered, but verify_receipt only checks header/digest consistency and explicitly does not validate calendar operations or Bitcoin inclusion, leaving agents to invoke external ots upgrade/verify for the real proof. No status lookup or receipt introspection is offered, though the stateless design limits what could be added.
