What is cc-bridge CLAUDE.md?

Development instructions for cc-bridge, an HTTP service that exposes an Anthropic-compatible API while running the official Claude Code command-line tool underneath. They cover setup, authentication, building, running, and testing the service.

Use them to install the required Claude Code CLI and Go environment, build cc-bridge, start it on a chosen port, and test its message endpoint with an HTTP request.

They help developers work around applications that cannot directly use Claude Code OAuth credentials for ordinary API requests. The official command-line tool remains responsible for authentication.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.04243	$0.04243
Opus 5.5	$0.01697	$0.01697

Security

Grade A, and why

cc-bridge CLAUDE.md scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

CLAUDE.md - CC-Bridge Development Guide

Project Overview

CC-Bridge is an HTTP service that provides 100% Anthropic API compatibility while using the official Claude Code CLI under the hood. This preserves OAuth access legitimately without authentication hacks.

Problem: Anthropic is shutting down third-party OAuth access. Apps using OAuth tokens directly now fail with:

LLM request rejected: This credential is only authorized for use with
Claude Code and cannot be used for other API requests.

Solution: Wrap claude -p (Claude CLI print mode) as an HTTP service. Let the official CLI handle authentication.

Quick Start

Prerequisites

Claude Code CLI installed:

npm install -g claude-code
# Verify
claude --version

Claude Code authenticated:

claude setup-token
# Follow OAuth flow or provide API key

Go 1.21+:
```
go version
```

Development Setup

# Clone/create project
cd cc-bridge

# Build
make build

# Run server (default port 8321)
./build/ccbridge

# Or with custom port
./build/ccbridge --port 9000

# Test
curl -X POST http://localhost:8321/v1/messages \
  -H "Content-Type: application/json" \
  -d '{"model": "claude-sonnet-4-20250514", "messages": [{"role": "user", "content": "Hello"}]}'

Architecture

Client (Anthropic SDK)
  ↓ POST /v1/messages
Go HTTP Server (cc-bridge)
  ↓ spawn("claude", ["-p", ...])
Claude CLI
  ↓ OAuth or API key
Anthropic API

Key insight: We're not fighting OAuth - we're delegating auth to the official tool that's allowed to use it.

Implementation Guide

Phase 1: Non-Streaming MVP (10-12 hours)

Goal: Basic request/response works with Anthropic SDK
