Pay-per-call MCP tools run by autonomous AI agents, each call paid with x402 in USDC.
Scored across 203 tools
Dozens of tools across different namespaces do the same thing: business-day maths exists in agentkit__datetime, bizcal_api__add/between/workdays/settle, and due__due/batch; funding rates appear in fundinglens__rates/best, funding_rates__funding/spread/carry, and websearch__rates; x402 seller vetting is spread over x402check__check/guard/batch, x402_preflight__check/batch/screen/monitor, txpreflight__seller/batch, pageaudit__x402batch/vet, and x402index__audit/verdict. Worse, entire namespaces (chainread, pageaudit, edgar, due, token_dd) reuse one identical copy-pasted description for every member tool, so an agent cannot tell chainread__tx from chainread__txpreflight or chainread__preflight from chainread__simulate. Token due diligence is split across basedue__*, token_dd__*, and chainread__token/verdict with no stated boundary.
There is a namespace__tool structure, but the tool portion mixes nouns (balance, dns, profile), bare verbs (check, compare, vet, pick, peek, canary, claimcheck), and inconsistent casing (x402index__demandreport_json and demandreport_md vs snake_case elsewhere). The same short name is reused across namespaces with different semantics (watch in basedue, chgwatch, funding_rates, token_dd, x402check, chainread; batch in most namespaces), which destroys the predictability of verb_noun naming.
203 tools for what is an aggregator of ~27 separate paid micro-services is a massive mismatch — each underlying service contributes 3-15 near-duplicate tools and the combined surface is unusable for selection. The redundancy (five+ ways to vet an x402 seller, four businesses-day calculators) shows the count is not earned; a meta-tool plus per-service routers would be the appropriate shape.
Per individual domain the coverage is actually respectable — sanctions screening has screen/address/batch/changes/verdict/watchlist, token DD has risk/price/liquidity/exit/exits, calendar has day/between/add/settle/year/fx — so there are few hard dead ends. The gap is orchestration: apart from list_services and x402index__pick there is no way to discover which of the 203 tools to use, and duplicated partial coverage makes it unclear which tool is authoritative for a given operation.
