Gcf Proxy

Overview

Gcf Proxy is a Model Context Protocol server that acts as a drop-in proxy to reduce token usage in your MCP workflows. It cuts token consumption by 71 percent, and when combined with session deduplication, achieves up to 92 percent efficiency gains. The proxy requires zero code changes to integrate into your existing setup.

The server runs locally on your machine using the npm package @blackwell-systems/gcf-proxy, which communicates over stdio. No authentication or credentials are needed to get started. Version v0.10.2 is available under the MIT license, with source code at blackwell-systems/gcf-proxy on GitHub.

Gcf Proxy belongs in the AI & Agents category and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing on mcp.site to verify ownership and keep information current.
