openclaw-claude-proxy (ocp)

If you already pay $20/mo for Claude Pro or $100/mo for Claude Max, you're leaving significant value on the table every time you also pay per-token through the Anthropic API.

openclaw-claude-proxy (ocp) fixes this. It's a zero-dependency, single-file Node.js proxy that:

• Exposes a standard OpenAI-compatible /v1/chat/completions endpoint on localhost:3456
• Routes requests through the claude CLI using your existing OAuth session
• Works with LangChain, Open WebUI, LlamaIndex, Cursor, or any app that speaks OpenAI
• $0 extra cost — uses your existing subscription

Cost Comparison

Setup (2 commands)

git clone https://github.com/dtzp555-max/openclaw-claude-proxy
cd openclaw-claude-proxy
node setup.mjs

No npm install needed. Auto-starts on login via launchd (macOS) or systemd (Linux).

Works With Any OpenAI Client

# LangChain
from langchain_openai import ChatOpenAI
llm = ChatOpenAI(base_url="http://localhost:3456/v1", api_key="none", model="claude-opus-4-6")

// OpenAI SDK
const openai = new OpenAI({ baseURL: 'http://localhost:3456/v1', apiKey: 'none' })

Also works with: Open WebUI, LlamaIndex, Cursor, or anything with an OpenAI-compatible endpoint setting.

Multiple Agents, One Subscription

Multiple OpenClaw agents or instances can share a single Claude Pro/Max subscription through ocp — no extra API keys per agent.

Honest Trade-offs

• Serial execution: The CLI worker pool runs requests one at a time, not in parallel. Higher latency than direct API.
• Personal use: Best for solo workflows, local agents, and tools where you're the only user.
• Claude CLI required: You need claude CLI installed and authenticated first.

Latest: v1.7.1

• v1.7.0: Optional Bearer token authentication (PROXY_API_KEY env var)
• v1.7.1: Crash recovery on network interruptions, ANTHROPIC_* env sanitization to prevent auth path pollution
