MCP Connectivity Overview

This directory provides examples and configuration files to help you connect MCP servers with Datu.
Datu uses the mcp-use package to implement MCP clients and manage connectivity.

Purpose

With Datu, you can connect to your MCP servers and use their tools through the Datu AI Analyst.

Enabling MCP Servers

To enable MCP connectivity, set the following environment variable (see also configurations.md):

export DATU_ENABLE_MCP=true

Alternatively, add it to your .env file:

DATU_ENABLE_MCP=true

Connecting MCP Servers

MCP servers are defined in a JSON configuration file (e.g. mcp_config.json). Each server entry specifies the command, arguments, and environment needed to start it.

Structure of mcp_config.json

      "command": "python",
      "args": ["-m", "datu.mcp.tools.sql_generator"],
