Datus MCP Server¶

Expose Datus's database and context search tools via the Model Context Protocol (MCP), enabling integration with Claude Desktop, Claude Code, and other MCP-compatible clients.

Server Modes:

Static Mode: Single datasource, suitable for Claude Desktop, CLI tools, or single-tenant HTTP/SSE server
Dynamic Mode: Multi-datasource HTTP/SSE server, supports all datasources via URL path

Supported Transport Modes:

http: Streamable HTTP (bidirectional, default)
sse: Server-Sent Events over HTTP (for web clients)
stdio: Standard input/output (for Claude Desktop and CLI tools)

Quick Start¶

Install Datus:

pip install datus-agent

Start the MCP server:

# Static Mode: Single datasource
uvx --from datus-agent datus-mcp --datasource <your datasource>
uvx --from datus-agent datus-mcp --datasource <your datasource> --transport http --host 127.0.0.1 --port 8000
# Dynamic Mode: Multi-datasource HTTP/SSE server
uvx --from datus-agent datus-mcp --dynamic --transport http --host 127.0.0.1 --port 8000
uvx --from datus-agent datus-mcp --dynamic --transport sse --host 127.0.0.1 --port 8000

# Or run directly
datus-mcp --datasource <your datasource>
# Dynamic Mode: Multi-datasource HTTP/SSE server
datus-mcp --dynamic --transport http --host 127.0.0.1 --port 8000
datus-mcp --dynamic --transport sse --host 127.0.0.1 --port 8000

Client Integration¶

Claude Code¶

Start the Datus MCP server, then add it to Claude Code:

# Start server (SSE mode)
datus-mcp --dynamic --transport sse --port 8000

# Add to Claude Code
claude mcp add --transport sse datus http://127.0.0.1:8000/sse/<your datasource>

Claude Desktop¶

Claude Desktop requires mcp-remote to connect to a remote MCP server.

Start the Datus MCP server, then configure Claude Desktop using the following script:

# npx may not be found directly by Claude Desktop, so we resolve the full paths
NODE_BIN_DIR=$(dirname $(which node))
NPX_PATH=$(which npx)

cat > ~/Library/Application\ Support/Claude/claude_desktop_config.json << EOF
{
  "mcpServers": {
    "datus-agent": {
      "command": "$NPX_PATH",
      "args": [
        "mcp-remote@latest",
        "http://127.0.0.1:8000/sse/<your datasource>",
        "--transport",
        "sse-only"
      ],
      "env": {
        "PATH": "$NODE_BIN_DIR:/usr/local/bin:/opt/homebrew/bin:/usr/bin:/bin"
      }
    }
  }
}
EOF

Or manually add the following to your claude_desktop_config.json:

{
  "mcpServers": {
    "datus-agent": {
      "command": "npx",
      "args": [
        "mcp-remote@latest",
        "http://127.0.0.1:8000/sse/<your datasource>",
        "--transport",
        "sse-only"
      ]
    }
  }
}

Tip

Claude Desktop also supports stdio transport directly. See the Other MCP Clients section for stdio configuration.

Other MCP Clients¶

For MCP clients that support stdio transport:

Using uvx:

{
  "mcpServers": {
    "datus": {
      "command": "uvx",
      "args": [
        "--from",
        "datus-agent",
        "datus-mcp",
        "--datasource",
        "<your datasource>",
        "--transport",
        "stdio"
      ]
    }
  }
}

Using python directly:

{
  "mcpServers": {
    "datus": {
      "command": "python",
      "args": [
        "-m",
        "datus.mcp_server",
        "--datasource",
        "<your datasource>",
        "--transport",
        "stdio"
      ]
    }
  }
}

For MCP clients that support HTTP/SSE transport:

SSE:

{
  "mcpServers": {
    "DatusServer": {
      "url": "http://127.0.0.1:8000/sse/<your datasource>",
      "transport": "sse"
    }
  }
}

Streamable HTTP:

{
  "mcpServers": {
    "DatusServer": {
      "url": "http://127.0.0.1:8000/mcp/<your datasource>",
      "transport": "http"
    }
  }
}

HTTP Server Mode¶

Static Mode (Single Datasource):

# Streamable HTTP (default, bidirectional)
datus-mcp --datasource <your datasource> --transport http --host 0.0.0.0 --port 8000

# SSE mode (for web clients)
datus-mcp --datasource <your datasource> --transport sse --port 8000

Connect to:

Streamable HTTP: http://localhost:8000/mcp
SSE: http://localhost:8000/sse

Dynamic Mode (Multi-Datasource):

Run a single server that supports all configured datasources via URL path:

# Start dynamic server with sse mode
datus-mcp --dynamic --host 0.0.0.0 --port 8000 --transport sse

# Start dynamic server with streamable HTTP mode
datus-mcp --dynamic --host 0.0.0.0 --port 8000 --transport http

Connect to specific datasource:

HTTP: http://localhost:8000/mcp/{datasource}
SSE: http://localhost:8000/sse/{datasource}
With subagent: http://localhost:8000/mcp/{datasource}?subagent={subagent_name}

Example:

Streamable HTTP, datasource bird_sqlite: http://localhost:8000/mcp/bird_sqlite
SSE, datasource bird_sqlite: http://localhost:8000/sse/bird_sqlite
Streamable HTTP, datasource superset, subagent sales_dashboard: http://localhost:8000/mcp/superset?subagent=sales_dashboard

Info endpoints:

http://localhost:8000/ - Server info and available datasources
http://localhost:8000/health - Health check
