## Tools (as reported by the server, not verified)

- `check\_x402\_endpoint`: Before paying an unknown x402 endpoint, check whether it is safe: liveness, trust score \(0-100\), anomaly flags \(receiver address changed between observations, catalog price vs. challenge price, invalid receiver, testnet listed as production, scheme outside the x402 spec\), receiver stability and obse
- `mcp\_check\_server`: Before installing an MCP server or npm package, audit it: does it run an INSTALL SCRIPT \(arbitrary code execution at \`npm i\`\), is it abandoned, does it ship a repository and license, weekly downloads, provenance — with a safe/caution/avoid verdict. \~11% of audited MCP servers run install scripts. Fr
- `mcp\_drift\_check`: The rug pull check. \`mcp\_check\_server\` answers whether a package is safe TODAY; this answers what CHANGED after it was adopted: an install script added in a later version \(arbitrary code on \`npm i\` that was not there at review time\), package ownership swapped, repository removed, package unpublished
- `mcp\_security\_report`: State of MCP Security: how many audited MCP servers run an arbitrary install script, are abandoned, ship no repository or license — with day-over-day deltas and a sample of currently-flagged servers. From a daily audit of the MCP server catalog. Free.
- `pulsefeed\_products`: List PulseFeed's paid products and how to pay via x402 \(USDC on Base\): deep trust check, endpoint track record, bulk trust dataset, full MCP drift series, the cross-domain Data API and on-chain token signals. Includes the client-side spend-cap gotcha for x402-fetch.
- `x402\_changes`: What changed in the x402 ecosystem recently: services that stopped returning a valid challenge, receiver \(payTo\) changes, price changes, recoveries, newly-seen services. Derived from compounding time-series that cannot be reconstructed after the fact. Free.
- `x402\_data\_sample`: FREE sample of the PulseFeed Data API: top-10 live x402 services as FULL records \(compounding payTo/price history, anomaly flags, on-chain receiver profile\), top-10 MCP servers with full audit profile, and 3 live incidents.
- `x402\_ecosystem\_stats`: Live health of the whole x402 agent-payment ecosystem: tracked/alive/dead counts, catalog-accuracy audit \(what share of listings called 'healthy' actually work\), risk-level distribution, receiver stability and on-chain receiver profiles. Free.
- `x402\_incidents`: Anomalies observed in live x402 endpoints by continuous independent measurement: receiver-address changes between observations, catalog price vs. challenge price mismatches, invalid receivers, testnet endpoints listed as production, payment schemes outside the x402 spec — EACH WITH AN ON-CHAIN REFER
- `x402\_leaderboard`: Top x402 services ranked by the open PulseFeed Trust Score \(0-100\), with price and network — the most reliable live agent-payment endpoints right now. Free.
- `x402\_working\_services`: List x402 agent-payment services that are currently ALIVE and return a valid x402 challenge, ranked by PulseFeed Trust Score, plus ecosystem risk map. Use this to pick a service with a track record instead of paying an endpoint you have not checked. Free.
