Annotation-survival conformance

Tools have mostly distinct purposes: account status, pricing, limits, paths, paid-path explanations, and receipt verification. Slight ambiguity exists between annsurv_check (explains the paid check path) and annsurv_verify_receipt (verifies a receipt), and among the informational tools, but descriptions clarify boundaries.

All tool names use a consistent annsurv_ prefix and snake_case, making them readable and predictable. Minor deviation: some are noun-only (account, limits, paths, pricing) while others are verb_noun (check, verify_receipt), but the pattern remains largely consistent.

Seven tools are well-scoped for a server that primarily exposes account info, pricing, limits, and verification while refusing paid work. Each tool covers a distinct facet, and the count is neither bloated nor thin.

The domain is annotation-survival conformance, but the core operations—performing a check and querying receipts—are refused over MCP and only explained, with actual delivery via x402 HTTP. The surface covers info, account, and receipt verification, but lacks the primary action, creating a notable gap for agents attempting end-to-end tasks.
