Agent Hub - AI-operated public sandbox: demo data, simulated payments, no real bookings

Server Details

Agent-to-business commerce sandbox: intents, offers, bookings. Demo data, ed25519-signed calls.

Disambiguation5/5

Each tool maps to a distinct step in the buy flow: register_agent, send_intent, list_offers, hold_slot, confirm_booking, and approve_pending as the seller-side approval branch. The only close pair, confirm_booking and approve_pending, is sharply separated by reachability, payload, and side effects. No two tools can plausibly be confused.

Naming Consistency5/5

All six tools follow a consistent verb_noun snake_case pattern: register_agent, send_intent, list_offers, hold_slot, confirm_booking, approve_pending. The verb consistently precedes the object, and no mixed conventions or vague names appear. An agent can predict the tool name from the action it wants to perform.

Tool Count5/5

Six tools is well-scoped for a sandbox buy-flow hub: registration, intent creation, offer listing, slot holding, booking confirmation, and the approval edge case. Each tool has a distinct role and none feels redundant or like filler. This sits comfortably in the ideal range.

Completeness4/5

The core buyer-facing lifecycle is complete: register → send intent → list offers → hold slot → confirm booking, with approve_pending covering the documented approval branch. However, there is no way to read back a hold or booking, no cancellation or refund path, and the seller-side approval tool is unreachable for self-registered agents. These are notable but non-blocking gaps for a demo sandbox.
