X711 — Universal Agent Gas Station
Let Claude or Cursor agents call paid third-party tools without you pre-funding every API—micropay per request via free tier, API key, or x402 USDC.
Overview
x711 Universal Agent Gas Station is a MCP server for the Build phase that meters and bills per-use tool API calls for AI agents via free tier, API key, or x402 USDC.
What is this MCP server?
- Remote streamable-http MCP at x711.io—no local server package required in the registry entry
- Three auth paths: free tier, API key, and x402 USDC micropayments
- Pay-per-use tool API designed as a shared wallet for multi-tool agent workflows
- Version 1.0.0 with website and schema-aligned server metadata
- Remote MCP URL: https://x711.io/mcp (streamable-http)
- Auth modes: free tier, API key, x402 USDC micropayments
- Registry version: 1.0.0
What problem does it solve?
Solo builders stitching many agent tools together waste time on separate billing accounts and fear runaway API spend on unattended agent loops.
Who is it for?
Indie builders running Claude Code or Cursor agents that call multiple external tools and want usage-based payment without enterprise procurement.
Skip if: Teams that need only one fixed API with a single key and no agent-side metering, or builders avoiding any paid or crypto settlement rails.
What do I get? / Deliverables
Your agent registers one remote MCP endpoint and routes tool usage through centralized quotas and micropayment options instead of juggling provider keys per integration.
- Configured remote MCP connection to https://x711.io/mcp
- Metered agent tool calls through x711 auth mode of your choice
