Overview

AI-generated overview

x402-vuln is a local stdio MCP server that exposes an x402 paid API for AI agents, settling payments in USDC on Base via a CDP facilitator.

What you can do
  • The listing provides no tool list, instructions or README, so the exact capabilities are undocumented.
  • The description frames it as an x402 paid API aimed at AI agents.
  • Payments are described as USDC on Base, processed through a CDP facilitator.
  • Beyond that, what the assistant can actually call cannot be determined from the supplied material.
When to use it
Only consider it if you specifically want an agent to reach an x402 pay-per-request API and are prepared to handle USDC payments on Base; otherwise the missing documentation makes it hard to justify.
Requirements
Runs as a local process over stdio, installed from the npm package x402-vuln, so a Node.js runtime is needed. Desktop client only; no web execution. No authentication, environment variables or headers are declared, though a CDP facilitator and a funded wallet are implied by the description.
Before you install
The server is described as a paid API settling in USDC on Base, so using it can spend real money from a crypto wallet; review pricing and spending limits first. No tools, instructions or README are published, so what it does with requests and credentials is unverifiable. No credentials are declared, but a CDP facilitator connection may involve account or key material.

Installation

In SourceWeft

  1. Open x402-vuln in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Tools

SourceWeft started this package once in an isolated sandbox, without credentials, to list its tools. That failed: the server did not answer in time.

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
