Claude Proxy

claude-proxy

claude-proxy is published on npm as @sunflower0305/claude-proxy. It is a lightweight Express proxy that lets Claude Code or the Claude Agent SDK talk to domestic Chinese LLM providers through Anthropic-compatible /v1/messages endpoints.

It currently supports qwen, deepseek, glm, minimax, kimi, and mimo.

The proxy reads configuration from environment variables. You can export them in your shell or create a .env file in the directory where you run claude-proxy; .env loading uses Node.js built-in .env file support.

Example .env:

Local Capture Logging

Capture logging is disabled by default. Enable it only for local debugging in a
trusted environment:

Each completed, failed, or client-aborted POST /v1/messages request is written
as one JSON file. With redaction enabled, Authorization and x-api-key
headers are replaced with [REDACTED].

Capture files still contain complete request and response bodies. Prompts,
messages, tool inputs and outputs, metadata, generated content, and other
sensitive payload data are not redacted. The capture store currently has no
body-size limit, file rotation, or retention policy, so long-running streams and
repeated requests can consume memory and disk space. Use this feature only for
short-lived debugging, protect the capture directory, and remove captures when
they are no longer needed.

You can use the bundled example as a starting point:

If you installed globally, create .env manually or export the variables in your shell before starting the proxy.
