Anthropic Proxy Rs — AI skill for Claude Code

anthropic-proxy-rs

High-performance Rust proxy that translates Anthropic API requests to OpenAI-compatible format. Use Claude Code, Claude Desktop, or any Anthropic API client with OpenRouter, native OpenAI, or any OpenAI-compatible endpoint.

Features

• Fast & Lightweight: Written in Rust with async I/O (~3MB binary)
• Full Streaming: Server-Sent Events (SSE) with real-time responses
• Tool Calling: Complete support for function/tool calling
• Universal: Works with any OpenAI-compatible API (OpenRouter, OpenAI, Azure, local LLMs)
• Extended Thinking: Supports Claude's reasoning mode
• Drop-in Replacement: Compatible with official Anthropic SDKs

Quick Start

**Note**: Using [Task](https://taskfile.dev) is currently recommended. Install with `brew install go-task` (macOS) or see the [installation guide](https://taskfile.dev/installation/). Releases with build binaries will be made soon.

# Install Rust (if needed)
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Build and install to PATH with task

task local-install

Install with curl

curl -fsSL https://raw.githubusercontent.com/m0n0x41d/anthropic-proxy-rs/main/install.sh | bash

This installer uses `cargo install --git ... --locked` under the hood, so Rust/Cargo still needs to be present on the machine.
