61 tested tools for AI agents: facts, payments, agent wallets, x402 market, work queues, contracts.
Scored across 62 tools
Many tools are individually well-described, but the set has overlapping clusters, especially 'check before spending' tools (alive, quote, preflight, tx_preflight, authorize, spend_gate, passport_check) and site/vendor fact tools (site_check, local_facts, vendor_check, agent_ready). Clear prefixes help, but an agent can still easily choose the wrong layer for payment or website questions.
All names use lowercase snake_case, with consistent resource prefixes for families such as queue_, ledger_, locker_, pobox_, market_, finance_, wallet_, terms_, passport_, and contract_. Minor deviations like alive, changed, quote, and dedupe are descriptive and readable, not chaotic.
At 62 tools, the surface is far beyond a typical well-scoped MCP server and forces substantial tool-selection overhead. Even as a broad agent-infrastructure suite, this is an extreme number of tools for one server.
Core lifecycle coverage is strong across queue, ledger, locker, PO box, passport, receipt, evidence, contract, and wallet/finance flows, with few obvious dead ends. Minor gaps remain, such as no explicit revoke/delete/cleanup tools for some resources and no public-key retrieval tool despite references to offline verification.
