Using with MCP Clients

Claude Desktop

To use this server with Claude Desktop, add the following configuration to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "revenuebase": {
      "command": "uv",
      "args": ["--directory", "/path/to/revenuebase-mcp-server", "run", "python", "server.py"],
      "env": {
        "REVENUEBASE_API_KEY": "your_api_key_here"
      }
    }
  }
}

Replace /path/to/revenuebase-mcp-server with the actual path to your cloned repository and your_api_key_here with your actual RevenueBase API key.

Other MCP Clients

For other MCP clients, you can connect to the server using the stdio transport. The server runs as a standard MCP server and accepts connections on stdin/stdout.

from mcp import ClientSession, StdioServerParameters
from mcp.client.stdio import stdio_client

server_params = StdioServerParameters(
    command="python",
    args=["server.py"],
    env={"REVENUEBASE_API_KEY": "your_api_key_here"}
)

async with stdio_client(server_params) as (read, write):
    async with ClientSession(read, write) as session:
        # Initialize the connection
        await session.initialize()
        
        # List available tools
        tools = await session.list_tools()
        print("Available tools:", [tool.name for tool in tools.tools])
        
        # Call a tool
        result = await session.call_tool("real_time_email_verification", {
            "email": "test@example.com"
        })
        print("Verification result:", result)
