CCProxy API Server

CCProxy is a local, plugin-based reverse proxy that unifies access to multiple AI providers (e.g., Claude SDK/API and OpenAI Codex) behind a consistent API. It ships with bundled plugins for providers, logging, tracing, metrics, analytics, and more.

Supported Providers

• Anthropic Claude API/SDK (OAuth2 flow or Claude CLI/SDK token files)
• OpenAI Codex (ChatGPT backend Responses API using OAuth for paid/pro accounts)
• GitHub Copilot (chat and completions for free, paid, or business accounts)

Each provider adapter exposes the same surface area: OpenAI Chat Completions, OpenAI Responses, and Anthropic Messages. The proxy maintains a shared model-mapping layer so you can reuse the same model identifier across providers without rewriting client code.

Authentication can reuse existing provider files (e.g., Claude CLI SDK tokens and the Codex CLI credential store), or you can run ccproxy auth login <provider> to complete the OAuth flow from the CLI; stored secrets are picked up automatically by the proxy.

Extensibility

CCProxy's plugin system lets you add instrumentation and storage layers without patching the core server. Bundled plugins currently include:

• access_log: structured access logging for client and provider traffic
• analytics: DuckDB-backed analytics APIs for captured request logs
• claude_api: Anthropic Claude HTTP API adapter with health and metrics
• claude_sdk: local Claude CLI/SDK adapter with session pooling
• codex: OpenAI Codex provider adapter with OAuth support
• command_replay: generates curl/xh commands for captured requests
• copilot: GitHub Copilot provider adapter with OAuth token management
• credential_balancer: rotates upstream credentials based on health
• dashboard: serves the CCProxy dashboard SPA and APIs
• docker: runs providers inside Docker via CLI extensions
• duckdb_storage: exposes DuckDB-backed storage for logs and analytics
• max_tokens: normalizes max_tokens fields to provider limits
• metrics: Prometheus-compatible metrics with optional Pushgateway
• oauth_claude: standalone OAuth provider for Claude integrations
• oauth_codex: standalone OAuth provider for Codex integrations
• permissions: interactive approval flow for privileged tool actions
• pricing: caches model pricing data for cost-aware features
• request_tracer: detailed request/response tracing for debugging

Shared helpers such as claude_shared provide metadata consumed by the Claude plugins. Each plugin directory contains its own README with configuration examples.

Plugin Config Quickstart

The plugin system is enabled by default (enable_plugins = true), and all discovered plugins load automatically when no additional filters are set. Use these knobs to adjust what runs:

• enabled_plugins: optional allow list; when set, only the listed plugins run.
• disabled_plugins: optional block list applied when enabled_plugins is not set.
• plugins.<name>.enabled: per-plugin flag (defaults to true) that you can override in TOML or environment variables. Any plugin set to false is added to the deny list alongside disabled_plugins during startup.

During startup we merge disabled_plugins and any plugins.<name>.enabled = false entries into a single deny list. At runtime the loader checks the allow list first and then confirms the plugin is not deny listed. Configure plugins under plugins.<name> in TOML or via nested environment variables.

Use ccproxy plugins list to inspect discovered plugins and ccproxy plugins settings <name> to review configuration fields.

Running

To install the latest stable release without cloning the repository, use uvx to grab the published wheel and launch the CLI:

uvx --with "ccproxy-api[all]" ccproxy serve --port 8000

If you prefer pipx, install the package (optionally with extras) and use the local shim:

pipx install "ccproxy-api[all]"
ccproxy serve # default on localhost:8000
