Overview

AI-generated overview

A local MCP server exposing 25 pay-per-call x402 API tools on Base mainnet, paid in USDC per request with no API keys or signup.

What you can do
Run paid research and analysis calls: AI answers, deep research, summaries, text analysis and competitor comparisons, each billed per call in USDC on Base mainnet after an HTTP 402 payment challenge and retry. Retrieve market and finance data: stock quotes, crypto prices, crypto research, macro dashboard, market pulse, treasury yields and Base gas snapshots. Pull filings and company information: SEC 10-K/10-Q analysis, EDGAR lookups, company intelligence dossiers and regulatory monitoring. Gather web and domain data: web search, URL text extraction, WHOIS/RDAP lookups, domain trust scores, news briefings and social sentiment. Run small utility operations: hashing, JSON-to-CSV conversion and,
When to use it
Use it when an assistant needs on-demand research, market, filing or web-lookup results and you are willing to pay small per-call USDC fees on Base mainnet instead of managing API keys or accounts.
Requirements
Runs as a local Node.js process installed from the npm package and started locally. An x402 client (the @x402/fetch and @x402/evm packages) is needed to make paid calls. A funded wallet holding USDC on Base mainnet is required, since payment replaces authentication. Network access to the provider's x402 server is needed.
Before you install
Every tool call costs real money in USDC on Base mainnet, from about $0.001 to $0.15 per call, so spending can add up quickly and is not reversible. Payment is the only authentication, so a funded wallet is exposed to the server's payment flow. Requests and their inputs are sent to the provider's remote x402 server, and results depend on that third-party service.

JMT x402 MCP Server

25 pay-per-call API tools for AI agents, powered by the x402 protocol on Base mainnet.

What This Does

This MCP server exposes 25 paid API endpoints as MCP tools. When an AI agent (Claude, Cursor, Cline) calls a tool, the request goes to our x402 server. The first request returns HTTP 402 (Payment Required). The agent's x402 client pays in USDC on Base mainnet and retries for the result.

No API keys. No signup. Payment IS the authentication.
