ccpkit

One command to switch between API providers for Claude Code and Codex CLI. Official API, relay/mirror, or your own self-hosted gateway — keep several profiles, switch instantly, verify with a built-in doctor.

Why

Claude Code reads ~/.claude/settings.json, Codex CLI reads ~/.codex/config.toml. Switching provider means editing those files by hand, remembering which key goes where, and breaking things when you switch back. ccpkit keeps every provider as a named profile and writes the right config for you — with automatic backups.

Features

• Named profiles for any provider: official, relay/mirror, self-hosted gateway
• One-command switch — ccpkit use <name>
• Writes both clients (Claude Code + Codex CLI) from a single profile
• doctor self-check — connectivity, latency, and model availability for every line
• Automatic backups of settings.json / config.toml before every write, ccpkit restore to roll back
• env output for people who prefer environment variables (bash / PowerShell / cmd)
• Zero dependencies, single file, Python 3.8+, Windows / macOS / Linux

Install

# 1) pipx (recommended)
pipx install ccpkit

# 2) pip
pip install ccpkit

# 3) uv
uvx ccpkit --help

# 4) no install at all — just download the single file
curl -LO https://raw.githubusercontent.com/kanfangwang/ccpkit/main/ccpkit.py
python ccpkit.py --help

# 5) Windows PowerShell one-liner
irm https://raw.githubusercontent.com/kanfangwang/ccpkit/main/ccpkit.py -OutFile ccpkit.py; python ccpkit.py --help

If pip cannot find it, your mirror may not have synced yet — add --index-url https://pypi.org/simple/ to pull straight from PyPI.

Quick start

# add a provider profile (interactive if you omit the flags)
ccpkit add myrelay \
  --claude-base https://api.example.com/p        --claude-key sk-xxx --claude-model claude-sonnet-4-6 \
  --codex-base  https://api.example.com/p/v1     --codex-key  sk-yyy --codex-model gpt-5.5

# save and switch to it
ccpkit add myrelay ... --use

# start from a preset instead (presets only pre-fill URLs; the key is always yours)
ccpkit presets
ccpkit add mdd --preset mdd --claude-key sk-xxx --codex-key sk-yyy --use
ccpkit add official --preset anthropic --claude-key sk-ant-... --use

# switch later
ccpkit use myrelay

# only one client
ccpkit use myrelay --client codex

# check every line: alive? latency? is my model there?
ccpkit doctor myrelay --models

# measure first-token latency and throughput (spends a few tokens)
ccpkit bench myrelay --runs 3
ccpkit bench myrelay --json

# list / inspect / remove
ccpkit list
ccpkit show myrelay
ccpkit remove myrelay

# prefer env vars instead of writing files?
ccpkit env myrelay --shell powershell

Example doctor output:

[myrelay]
  Claude OK  延迟 43 ms     (接口可用,未返回模型清单)
  Codex  OK  延迟 50 ms     模型 1 个 模型可用
          - gpt-5.5
全部正常

Example bench output (--runs 2, streaming):

$ ccpkit bench myrelay --runs 2
! 将发起 4 次真实请求(会产生少量用量),prompt: 'Reply with exactly: OK'
  Claude #1  首字 1785 ms    总耗时 1.78s   输出 1 tok   -
  Claude #2  首字 2119 ms    总耗时 2.12s   输出 1 tok   -

线路      成功率       首字均值        首字最快    总耗时均值  输出tok
--------------------------------------------------------------------
Claude    2/2       1952 ms     1785 ms     1.95 s      1

Numbers are illustrative and vary a lot by provider and time of day — the same relay has been measured anywhere from 0.7 s to 27 s first-token in a single session, which is exactly why the bench command exists.

bench also takes --json for machine-readable output, --no-stream for gateways without SSE, --runs N, and --prompt "..." to test your own workload.

Providers & presets

Works with any Anthropic-compatible or OpenAI-compatible endpoint: official APIs, relays/mirrors, or your own gateway. Built-in presets only pre-fill base URLs and a default model — your key is always your own: docs/providers.md.

Preset	Claude base	Codex base
anthropic	https://api.anthropic.com	–
openai	–	https://api.openai.com/v1
mdd (alias mdd-relay)	https://api.mddtech.cn/p	https://api.mddtech.cn/p/v1

What it writes

Client	File	What changes
Claude Code	~/.claude/settings.json	merges an env block: ANTHROPIC_BASE_URL, ANTHROPIC_AUTH_TOKEN, ANTHROPIC_MODEL
Codex CLI	~/.codex/config.toml	adds a managed block (model, model_provider, [model_providers.ccpkit] with base_url / env_key / wire_api)
Codex CLI	~/.codex/auth.json	sets OPENAI_API_KEY

Existing files are never destroyed: a timestamped *.ccpkit-bak-<time> copy is made first, and everything outside the managed block is left untouched.

# >>> ccpkit begin
model = "gpt-5.5"
model_provider = "ccpkit"

[model_providers.ccpkit]
name = "ccpkit"
base_url = "https://api.example.com/p/v1"
env_key = "OPENAI_API_KEY"
wire_api = "responses"
# <<< ccpkit end

Environment variables

Variable	Meaning
CCPKIT_HOME	where profiles.json lives (default ~/.ccpkit)
CCPKIT_CLAUDE_DIR	override the Claude home dir (default ~)
CCPKIT_CODEX_DIR	override the Codex home dir (default ~)
NO_COLOR	disable colored output

Handy for testing without touching your real config:

CCPKIT_HOME=/tmp/t CCPKIT_CLAUDE_DIR=/tmp/t CCPKIT_CODEX_DIR=/tmp/t ccpkit add test --use ...

Privacy

• No telemetry, no analytics, no network calls except the ones you trigger with doctor / model listing.
• Keys are stored locally in ~/.ccpkit/profiles.json (chmod 600 on POSIX).
• Nothing is uploaded anywhere.

FAQ

How do I go back to the official API? ccpkit add official --claude-base https://api.anthropic.com --claude-key sk-ant-... then ccpkit use official. Prefer your previous file? ccpkit restore --client claude.

Codex CLI ignores my model provider. Codex CLI must be restarted (open a new terminal). Also make sure ~/.codex/auth.json or OPENAI_API_KEY is set.

doctor says "接口可用,未返回模型清单". Some gateways don't expose a model list. The auth check still passed — that is normal.

Windows shows garbled characters. Use Windows Terminal, or set chcp 65001. The tool falls back to ASCII markers on legacy code pages.

Roadmap

• ccpkit usage — daily token / cost report from local session logs
• Publish to PyPI so pipx install ccpkit works without cloning
• Homebrew / Scoop formula
• ccpkit switch — swap only the model, keep the provider

中文说明

ccpkit 用来管理 Claude Code / Codex CLI 的多套 API 线路(官方、中转、自建网关),一条命令切换。

# 添加一条线路(不加参数会进入交互式问答)
ccpkit add 我的中转 \
  --claude-base https://api.example.com/p     --claude-key sk-xxx --claude-model claude-sonnet-4-6 \
  --codex-base  https://api.example.com/p/v1  --codex-key  sk-yyy --codex-model gpt-5.5

ccpkit use 我的中转        # 切换(写入两个客户端配置)
ccpkit doctor 我的中转      # 自检:连通性 / 延迟 / 模型是否可用
ccpkit list                # 查看所有线路,带 * 的是当前生效
ccpkit env 我的中转 --shell powershell   # 只想用环境变量,不写文件
ccpkit restore --client claude           # 恢复上次的配置备份

它写的文件

• Claude Code:~/.claude/settings.json 的 env 段(ANTHROPIC_BASE_URL / ANTHROPIC_AUTH_TOKEN / ANTHROPIC_MODEL)
• Codex CLI:~/.codex/config.toml 的托管块 + ~/.codex/auth.json 的 OPENAI_API_KEY

安全:每次写入前自动备份为 *.ccpkit-bak-<时间>,只改托管块,不动你其它配置;key 只存在本地 ~/.ccpkit/profiles.json,无任何上报。
