PostgreSQL MCP Server (Cloudflare Worker)

Get started:

Alternatively, you can use the command line below to get the remote MCP Server created on your local machine:

npm create cloudflare@latest -- my-mcp-server --template=https://github.com/Stratus-Cyber/postgres-mcp-cloudflare.git

⚠️ Currently, the Deploy to Cloudfare button does not support configuration of evironment variables, the variable must be configured manually, after deployment.

Connect to Cloudflare AI Playground

You can connect to your MCP server from the Cloudflare AI Playground, which is a remote MCP client:

1. Go to https://playground.ai.cloudflare.com/

2. Enter your deployed MCP server URL (postgres-mcp-server.<your-account>.workers.dev/sse)

3. You can now use your MCP tools directly from the playground!

Connect Claude Desktop to your MCP server

You can also connect to your remote MCP server from local MCP clients, by using the mcp-remote proxy.

To connect to your MCP server from Claude Desktop, follow Anthropic's Quickstart and within Claude Desktop go to Settings > Developer > Edit Config.

Update with this configuration:

{
  "mcpServers": {
    "calculator": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "http://localhost:8787/sse"  // or remote-mcp-server-authless.<your-account>.workers.dev/sse
      ]
    }
  }
}

Restart Claude and you should see the tools become available.

Connect Cursor AI to your MCP server

On Mac OS, go to Cursor > Settings > Cursor Settings > MCP > Add new Global MCP Server > edit the mcp.json file

{
  "mcpServers": {
    "postgresql-remote-mcp": {
      "url": "https://postgres-mcp-server.<your-account>.workers.dev/sse"
    }
  }
}
