Connect io.github.Nikolife2016/pulsefeed-x402 and your agent gets 11 tools, among them check_x402_endpoint, mcp_check_server, mcp_drift_check. It answers at https://pulsefeed.dev/mcp-server over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 20 October 2026, succeeded.
Verify x402 payment endpoints before an AI agent pays: scam scan, on-chain checks, trust scores.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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 Inputs: url |
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 Inputs: package |
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), packag Inputs: packages, days |
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 cat |
pulsefeed_products | List PulseFeed's products. All data endpoints are FREE since 2026-09-02 (trust checks, track records, datasets, drift history); only on-chain token signals are x402 pay-per-call. Formerly: deep trust check, endpoint track record, bulk trust |
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 afte Inputs: days |
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. Fr |
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 Inputs: days |
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 |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://pulsefeed.dev/mcp-server. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.nikolife2016. Endpoint host: pulsefeed.dev. ARD identifier: urn:air:io.github.nikolife2016:mcp:pulsefeed-x402.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
