Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@apibase11/mcp-client) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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.
