@entroute/mcp-server

MCP Server for AI agents to discover and call pay-per-request APIs via EntRoute.

Give Claude, Cursor, Windsurf, or any MCP-compatible agent access to 350+ verified x402 API endpoints across 110+ capabilities — DeFi prices, web search, prediction markets, news, and more.

Install

Claude Code

claude mcp add entroute -- npx @entroute/mcp-server

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "entroute": {
      "command": "npx",
      "args": ["@entroute/mcp-server"],
      "env": {
        "ENTROUTE_API_URL": "https://api.entroute.com"
      }
    }
  }
}

Cursor / Windsurf

Add to your MCP settings with command npx @entroute/mcp-server.

Tools

discover_paid_api

Find ranked, verified API endpoints for any capability. Supports natural language intent or explicit capability IDs.

"Find me an API to get the current price of ETH"
→ Returns ranked endpoints with pricing, success rates, and latency metrics

list_capabilities

Browse all available capability types. Filter by tag or search by keyword.

call_paid_api

Execute a discovered endpoint. Optionally handles x402 payments automatically when a wallet is configured.

Payment (Optional)

To enable automatic x402 payments, set these environment variables:

EVM_PRIVATE_KEY=0x...          # Wallet private key for USDC payments on Base
MAX_PAYMENT_PER_REQUEST=0.05   # Max USD per request (default: $0.05)

Without a wallet, the server still discovers endpoints — you just can't auto-pay for 402-protected ones.

Environment Variables

Variable	Default	Description
ENTROUTE_API_URL	https://api.entroute.com	EntRoute API base URL
EVM_PRIVATE_KEY	—	Hex private key for x402 payments
MAX_PAYMENT_PER_REQUEST	0.05	Spending cap per request in USD

Example Usage

Once installed, ask your agent:

• "What APIs are available for DeFi?"
• "Find me a web search API"
• "Get the current price of ETH using a paid API"
• "Search the news for AI agent developments"

The agent will use discover_paid_api to find endpoints, show you the options with pricing, and call the best one.
