Dgraph MCP (Master Control Protocol)

Project Overview

This is a Dgraph-based Master Control Protocol (MCP) designed to provide advanced graph database management and querying capabilities. There are two ways you can access the mcp server:

1. Using the dgraph alpha's http endpoint
2. Using the go code

Key Components

• Dgraph schema management
• Advanced data querying
• Flexible graph database interactions

Setup Instructions for dgraph alpha

• Install dgraph alpha
• Start dgraph alpha

For Read only:

{
  "dgraph-mcp-ro": {
    "serverUrl": "http://localhost:8080/mcp-ro/sse"
  }
}

For Read write:

{
  "dgraph-mcp": {
    "serverUrl": "http://localhost:8080/mcp/sse"
  }
}

Setup Instructions for go code

• Install dgraph binary
• Insert the following to your mcp config:

{
  "mcpServers": {
    "dgraph": {
      "command": "dgraph_binary",
      "args": ["mcp", "-c", "dgraph://localhost:9080"]
    }
  }
}

• Modify the server details using args in dgraph mcp command

Local Setup for Claude Desktop

You can setup a local experience using Claude app

Install Claude.app from https://claude.ai/download.

On Mac OS the configurations files are in ~/Library/Application\ Support/Claude. Create ~/Library/Application\ Support/Claude/claude_desktop_config.json file and set the content with mcp config shown above.

Close the Claude app and reopen it.

Check that the tools are listed in Claude desktop (Click on the tools icon).

You are ready to chat and get things done in Dgraph from Claude.

Troubleshooting

• Check Dgraph connection settings
• Verify Go module dependencies
• Review error logs carefully
