deadchannel-mcp

Check an x402 endpoint before you pay it.

An agent with a wallet can now buy from strangers. Nothing checks the stranger. deadchannel_probe grades an endpoint for $0.005 in USDC on Base — less than the smallest payment it protects — and returns a verdict, a risk score, and the specific findings behind both.

live      answers, settles, priced as listed
degraded  answers, but something is wrong
trap      takes payment and returns nothing usable
testnet   a testnet address advertised as mainnet
dead      does not answer at all

Install

{
  "mcpServers": {
    "deadchannel": {
      "command": "npx",

      "env": { "DEADCHANNEL_PRIVATE_KEY": "0x..." }
    }
  }
}

The key signs payments locally and never leaves the machine; only a signature is sent. Point it at a wallet holding a little USDC on Base — a dollar buys a thousand checks. deadchannel_health needs no key at all, so you can tell "the service is down" apart from "my key is wrong" before spending anything.
