Overview

Description from the maker (original English)

Verify x402 payment endpoints before an AI agent pays: scam scan, on-chain checks, trust scores.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

ChatGPT connects only to servers on the internet:

Open ChatGPT on the web → Settings → Connectors (Apps)
Press Create or Add (some plans need Developer mode under Advanced first)
Paste the address below, give it a name and save
If it asks you to sign in, sign in with the maker

https://pulsefeed.dev/mcp-server

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Pulsefeed X402 safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

PulseFeed

Verify before you pay or install.

Two questions an agent has to answer before it acts, and neither is answered by a scanner that only looks at the present:

Is this x402 endpoint safe to pay? — liveness, a 0–100 trust score, scam flags (receiver swapped, catalog price ≠ challenge price, honeypot receiver, testnet listed as production), with a pay/avoid verdict and on-chain proof links on Base.
**Did this MCP server or npm package change *after* people adopted it?** — an install script added in a later version, ownership swapped, repository removed, package unpublished, build provenance lost.

The second question is the one static scanners cannot answer. A rug pull is clean at review time by construction: the package collects installs for weeks, and only then ships the patch that runs code on npm i. Answering it requires yesterday's snapshot to exist, which is why the series here starts on 2026-07-30 and cannot be reconstructed after the fact.

PulseFeed re-audits the whole MCP registry every night and diffs it against the previous day's snapshot, and re-probes the x402 endpoint population daily. Everything below is free, needs no key, and no account.

MCP server

Hosted, no install:

https://pulsefeed.dev/mcp-server

Streamable HTTP. Also on the official MCP registry, Smithery and Glama.

Or run it locally — see mcp/:

npx pulsefeed-x402-mcp

Tools include check_x402_endpoint (is this endpoint safe to pay), mcp_check_server (audit before installing), mcp_drift_check (the rug-pull check — pass your own dependency list), mcp_security_report, x402_incidents and x402_changes.

Drift badge

Put it in your README. It states what changed in your package after people adopted it:

[![MCP drift](https://pulsefeed.dev/badge/mcp.svg?package=YOUR-PACKAGE)](https://pulsefeed.dev/mcp/drift)

Use your registry name (io.github.you/your-server) or your npm package name.

A green badge is a public claim about your package, so it is only issued when the package is actually in our snapshot. When it is not, the badge reads `unwatched` in grey — never green. Reporting absence of measurement as evidence of cleanliness is a mistake we made once publicly and will not repeat; see the correction.

CI check

Fails the build when something you already depend on changes dangerously:

- uses: Nikolife2016/mcp-drift-action@v1

Marketplace · source. Run it on a schedule, not only on pull requests — drift happens between your commits.

Free API

No key, CORS enabled, safe to call from a browser or a catalog page:

# what changed, whole registry

curl -s "https://pulsefeed.dev/mcp/drift.json?days=7"

only your dependencies

curl -s "https://pulsefeed.dev/mcp/drift.json?packages=pkg-a,pkg-b&days=7"

is this x402 endpoint payable

curl -s "https://pulsefeed.dev/verify?endpoint= "

Subscribe without signing up — the filter lives in the URL, so there is no subscriber database and nothing to leak:

On being wrong in public

We once published that 76% of x402 endpoints were dead. That measured our own parser, not the market, and the figure was corrected twice more after that — each time downward, each time for the same class of reason: our own behaviour recorded as somebody else's track record. The whole mechanism, every correction and the checklist that came out of it are kept at pulsefeed.dev/correction rather than quietly deleted.

If you find a number here that does not hold, open an issue — that page is where it will end up.
