Is pulsefeed-x402 live?

Yes — it answered the hub's last check (checked 22m ago). It answered 100% of checks over the last 30 days.

Is pulsefeed-x402 free to use?

Yes — the hub reached it with no key and no payment.

What tools does pulsefeed-x402 have?

11 tools: check_x402_endpoint, mcp_check_server, x402_data_sample, x402_leaderboard, x402_ecosystem_stats, x402_changes, pulsefeed_products, x402_working_services, ….

Is pulsefeed-x402 safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• check_x402_endpoint reads open 22m ago

  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 observation-count-qualified uptime — with a pay/avoid verdict. Reads the challenge from both the response body and the v2 PAYMENT-REQUIRED header. Free.

• mcp_check_server reads open 22m ago

  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. Free.

• mcp_drift_check reads open 7h ago

  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(arbitrary code on `npm i` that was not there at review time), package ownership swapped, repository removed, package unpublished, build provenance lost. Pass your own dependency list to check it in one call. Derived from a daily external re-audit of the whole MCP package population — an event exists only because a snapshot from before it exists. Free.
