CCP

CCP is a local CLI and HTTP proxy for using Claude Code with configurable model providers through an Anthropic-compatible endpoint.

It is not a Claude login bypass. It uses Claude Code's supported ANTHROPIC_BASE_URL and ANTHROPIC_API_KEY path.

Build

go build -o .\bin\ccp.exe .\cmd\ccp

Configure

Copy configs/config.example.yaml to ~/.ccp/config.yaml or pass it explicitly with --config.

Provider keys can be direct values or environment references:

api_key: ${DEEPSEEK_API_KEY}
api_key: sk-local-value

Each provider can also control its own outbound proxy:

providers:
  openai:
    type: openai-compatible
    base_url: https://api.openai.com
    api_key: ${OPENAI_API_KEY}
    proxy:
      enabled: true
      url: http://127.0.0.1:7897

Set proxy.enabled: false or omit the block to connect directly.

Concurrency Protection

CCP supports global and per-provider concurrency limits so a burst of Claude Code or subagent requests does not exhaust the local proxy process:

server:
  max_concurrent_requests: 64

providers:
  openai:
    max_concurrent_requests: 16

When a limit is full, CCP waits briefly for capacity. If no slot becomes available, it returns 503 busy instead of letting the proxy overload.

Recommended local setup:

$env:DEEPSEEK_API_KEY="<set-this-in-your-current-shell>"

Default DeepSeek aliases:

aliases:
  haiku: deepseek-anthropic:deepseek-v4-flash
  sonnet: deepseek-anthropic:deepseek-v4-pro
  opus: deepseek-anthropic:deepseek-v4-pro

Validate

.\bin\ccp.exe --config .\configs\config.example.yaml doctor
.\bin\ccp.exe --config .\configs\config.example.yaml test haiku "hello"

Run With Claude Code

Start the proxy:

.\bin\ccp.exe --config .\configs\config.example.yaml serve

In another shell:

$env:ANTHROPIC_BASE_URL="http://127.0.0.1:8787"
$env:ANTHROPIC_API_KEY="local-dev-key"
claude

You can print the environment commands with:

.\bin\ccp.exe --config .\configs\config.example.yaml env

Logs

Default request log:

~/.ccp/logs/ccp.log

Default usage log:

~/.ccp/logs/usage.jsonl

Prompts and full API keys are not logged by default.
