agentreader-mcp

MCP server for AgentReader — 13 pay-per-call tools for AI agents (web intelligence, OFAC sanctions screening, x402 trust data), paid automatically in USDC on Base via the x402 protocol. No API keys, no accounts: your agent's wallet pays $0.001–$0.05 per call and failed requests are never charged.

Setup

You need a wallet holding a little USDC on Base mainnet ($1 covers hundreds of calls). Use a dedicated agent wallet, not your main one.

Claude Desktop / Claude Code / any MCP client:

{
  "mcpServers": {
    "agentreader": {
      "command": "npx",
      "args": ["-y", "agentreader-mcp"],
      "env": { "AGENTREADER_PRIVATE_KEY": "0xYourAgentWalletPrivateKey" }
    }
  }
}

Also listed in the official MCP Registry as io.github.ajanani1/agentreader-mcp and on npm.

Environment variables:

• AGENTREADER_PRIVATE_KEY (required) — private key of the paying wallet (USDC on Base; gas not needed, x402 uses gasless USDC authorizations)

• AGENTREADER_API (optional) — API base URL, default https://agentreader.dev

How payment works

Each tool call hits the AgentReader API, receives an HTTP 402 with x402 payment requirements, signs a USDC authorization with your key, and retries. Settlement happens through the Coinbase CDP facilitator on Base mainnet. Errors (4xx/5xx) never settle — you only pay for delivered results.

API without MCP

The same endpoints are callable directly over HTTP with any x402 client: catalog · OpenAPI · llms.txt · x402 discovery
