Provides deployment and hosting of the MCP server on Cloudflare Workers, with integration to Cloudflare AI Playground for testing and development.
Enables interaction with PostgreSQL databases through a remote MCP server, allowing AI agents to query and manipulate data in PostgreSQL instances.
PostgreSQL Remote Cloudflare MCP Worker
Get started:
Alternatively, you can use the command line below to get the remote MCP Server created on your local machine:
⚠️ Currently, the
Deploy to Cloudfare
button does not support configuration of evironment variables, the variable must be configured manually, after deployment.
Environment Variables
From the Cloudflare console > select your Worker AI, go to Settings > Variables and Secrets > +Add
Type: Secret
Variable Name: DATABASE_URL
Value: postgresql://<connection string>
Connect to Cloudflare AI Playground
You can connect to your MCP server from the Cloudflare AI Playground, which is a remote MCP client:
- Go to https://playground.ai.cloudflare.com/
- Enter your deployed MCP server URL (
postgres-mcp-cloudflare.<your-account>.workers.dev/sse
) - 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:
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
This server cannot be installed
A Cloudflare Worker that provides a Model Context Protocol (MCP) interface for PostgreSQL databases, allowing AI assistants like Claude and Cursor to interact with PostgreSQL databases through natural language.
