How do I use mmex-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@mmex-mcp show me my checking account balance" That's it!

{
  "mcpServers": {
    "mmex-mcp": {
      "command": "mmex-mcp",
      "env": {
        "MMEX_DB_PATH": "/path/to/your/database.mmb"//Optional

    }
  }
}

For clients that support stdio MCP servers:

MMEX_DB_PATH=/path/to/file.mmb mmex-mcp

The MCP Inspector provides a web UI to test all tools interactively:

MMEX_DB_PATH=/path/to/file.mmb npx @modelcontextprotocol/inspector mmex-mcp

This will:

Start the MCP server
Launch the MCP Inspector web UI
