Setup
Install MCP Cat PSQL in your MCP client (Claude Desktop, Cursor, Windsurf, and others).
Repository: https://github.com/admin-curv/mcp-cat-psql
Follow the installation instructions in the repository README, then restart your MCP client.
Building a Remote MCP Server on Cloudflare (Without Auth)
This example allows you to deploy a remote MCP server that doesn't require authentication on Cloudflare Workers.
This will deploy your MCP server to a URL like:remote-mcp-server-authless.<your-account>.workers.dev/sse
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=cloudflare/ai/demos/remote-mcp-authless
To add your owntoolsto the MCP server, define each tool inside theinit()method ofsrc/index.tsusingthis.server.tool(...).
You can connect to your MCP server from the Cloudflare AI Playground, which is a remote MCP client:
- Go tohttps://playground.ai.cloudflare.com/
- Enter your deployed MCP server URL (remote-mcp-server-authless.<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 themcp-remote proxy.
To connect to your MCP server from Claude Desktop, followAnthropic's Quickstartand within Claude Desktop go to Settings > Developer > Edit Config.
{ "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.
