APIbase MCP Client

MCP client for APIbase.pro — connect AI agents to 300+ tools across 84 providers via the Model Context Protocol. Dual-rail payments: x402 (USDC on Base) + MPP (USDC on Tempo/Stripe).

Available as two identical packages:

Package	Install
@apibase11/mcp-client	npx -y @apibase11/mcp-client
apibase-mcp-client	npx -y apibase-mcp-client

Quick Start

npx -y apibase-mcp-client

Usage

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "apibase": {
      "command": "npx",
      "args": ["-y", "@apibase11/mcp-client"]
    }
  }
}

With API key:

{
  "mcpServers": {
    "apibase": {
      "command": "npx",
      "args": ["-y", "@apibase11/mcp-client", "ak_live_YOUR_KEY"]
    }
  }
}

Or via environment variable:

{
  "mcpServers": {
    "apibase": {
      "command": "npx",
      "args": ["-y", "@apibase11/mcp-client"],
      "env": {
        "APIBASE_API_KEY": "ak_live_YOUR_KEY"
      }
    }
  }
}

Cursor / Windsurf / VS Code

Same config pattern — add to your MCP settings:

{
  "command": "npx",
  "args": ["-y", "apibase-mcp-client"]
}

Streamable HTTP (no client needed)

Most modern MCP clients support remote servers directly:

{
  "mcpServers": {
    "apibase": {
      "url": "https://apibase.pro/mcp"
    }
  }
}

Authentication

Three modes (in priority order):

• CLI argument: npx apibase-mcp-client ak_live_YOUR_KEY
• Environment variable: APIBASE_API_KEY=ak_live_YOUR_KEY
• Auto-register: omit the key — APIbase creates one automatically on first request

Payment

APIbase supports dual-rail payments — agents can pay using either protocol:

Protocol	Network	Token	How
x402	Base	USDC	X-Payment header
MPP	Tempo (Stripe)	USDC	Authorization: Payment header

Free tools work without payment. Paid tools return HTTP 402 with payment instructions for both protocols. Use mppx SDK or Tempo CLI for automatic payment handling.

# AgentCash — one-command setup

How It Works

Stdio-to-HTTP bridge: translates MCP stdio transport (used by Claude Desktop, Cursor, etc.) to Streamable HTTP transport (used by APIbase server). No tool re-registration — pure transport proxy.
