litecc-proxy

Anthropic Messages API proxy that lets Claude Code talk to a LiteLLM-hosted model (e.g. Qwen 3.5) instead of the real Anthropic API.

Handles streaming, tool use, and rewrites raw <think>...</think> text (which reasoning models like Qwen emit inline, and which otherwise breaks Claude Code's rendering) into proper Anthropic thinking content blocks. Any number of <think> spans in a single response or stream are supported.

Run it

Without installing anything, straight from PyPI:

uvx litecc-proxy start --port 4000 \
  --litellm-base-url http://11.11.11.11:4000 \
  --litellm-model qwen-3.5

Straight from this git repo, without cloning:

uvx --from git+https://github.com/seong-hun/litecc-proxy litecc-proxy start --port 4000 \
  --litellm-base-url http://11.11.11.11:4000 \
  --litellm-model qwen-3.5

From a local checkout, with uv:

uv sync
uv run litecc-proxy start --port 4000 --litellm-base-url http://11.11.11.11:4000 --litellm-model qwen-3.5

Every flag also has an env-var equivalent, so you can drop them in .env instead:

Flag	Env var	Default
`--port`	`PROXY_PORT`	`8787`
`--host`	`PROXY_HOST`	`0.0.0.0`
`--litellm-base-url`	`LITELLM_BASE_URL`	`http://localhost:4000`
`--litellm-model`	`LITELLM_MODEL`	`qwen-3.5`
`--litellm-api-key`	`LITELLM_API_KEY`	(empty)
`--timeout`	`LITELLM_TIMEOUT`	`600` (seconds)
`--log-level`	`LOG_LEVEL`	`INFO`

CLI flags take precedence over env vars.

Point Claude Code at it

In Claude Code's settings.json:

{
  "env": {
    "ANTHROPIC_BASE_URL": "http://localhost:4000"
  }
}

(match the port to whatever you passed to --port.)

Publishing to PyPI

Publishing is automated via GitHub Actions + PyPI Trusted Publishing (OIDC): pushing a v*.*.* tag builds the package and publishes it, no API token needed.

git tag v0.1.0
git push origin v0.1.0

After that, uvx litecc-proxy start --port 4000 works for anyone without a local checkout.
