AgentBIT MCP Server

M8ven Score

Remote MCP server exposing 50+ pay-per-call API tools for AI agents — paid per request with USDC on Base via the x402 protocol (no accounts, no API keys, no subscriptions). First call is free for new wallets on most tools, and a couple of high-frequency tools are completely free.

Connect

Claude Desktop / any MCP client with remote server support:

{
  "mcpServers": {
    "agentbit": {
      "type": "streamable-http",
      "url": "https://agentbit.app/mcp"
    }
  }
}

tools/list works immediately. Two things are free — no wallet, no payment:

  • agentbit_discover — search 7,000+ indexed x402 resources across the whole ecosystem (Coinbase Bazaar, Agent402, Agentic Market) with price and real usage metrics.

  • onchain-gas — the live Base gas price, EIP-1559 base fee and latest block. The onchain heartbeat every agent checks before it transacts.

How payment works

Paid tools follow x402 v2: call a tool without payment and the response returns the exact payment requirements (price in USDC atomic units, network eip155:8453, pay-to address) as structured content. Sign an EIP-3009 USDC authorization with your agent's wallet and retry with the _payment argument — settlement is gasless for the buyer and runs through the Coinbase CDP facilitator. The x402-fetch-pay npm package does the whole loop in one call.

  • Prices per call: $0.0005 – $0.10 USDC (plus two free tools)

  • First call free for brand-new wallets (tools priced ≤ $0.02)

  • Volume discounts advertised in every 402 envelope (100 calls/30d → −10%, 1000 → −20%)

  • Per-tool reliability stats (success rate, p50/p95 latency) published in the catalog

Also available as plain HTTP

Every tool is a REST endpoint under https://agentbit.app/v1/... speaking x402 v2 directly — indexed in Coinbase Bazaar, Agent402, x402 Arena and other x402 discovery services, and searchable for free at /api/discover. The MCP server and the REST API are the same catalog.
