Gcf Proxy MCP Server

Bidirectional MCP proxy that translates between JSON and GCF. Drop-in, zero changes to your server or client. Works with any structured data format. It runs locally over stdio via the published package.

People connecting this server to Claude, Cursor, VS Code, or another MCP client. The project is written in Go.

01 · Install Gcf Proxy

Claude Code

claude mcp add blackwell-systems-gcf-proxy -- npx -y @blackwell-systems/gcf-proxy

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "blackwell-systems-gcf-proxy": {
      "command": "npx",
      "args": [
        "-y",
        "@blackwell-systems/gcf-proxy"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
