nvd-claude-proxy 1.1.5

Run Claude Code (and any Anthropic SDK client) on NVIDIA NIM models via a local proxy.

nvd-claude-proxy

Run Claude Code — and any Anthropic SDK client — on enterprise-grade NVIDIA NIM models.

nvd-claude-proxy is a production-hardened local HTTP proxy that translates between the Anthropic Messages API and the NVIDIA NIM (OpenAI-compatible) API. It enables you to run Claude Code, the Anthropic SDK, and other clients using high-performance NVIDIA-hosted models with official-grade resilience and scaling.

🚀 Key Features

• Architectural Excellence: Fully decoupled core translation logic from the transport layer.
• Enterprise Resilience: Built-in Circuit Breakers and automated failover chains to protect against upstream outages.
• Scalable State: Distributed session management via Redis (with SQLite and In-Memory fallbacks).
• Official-Grade Security: Unified AuthMiddleware protecting all endpoints with global API key enforcement.
• Claude Code Optimized: Specifically tuned for Claude Code's complex tool-calling and reasoning patterns.
• Modular Pipeline: Event-driven streaming architecture for deterministic state management.

🛠 Deployment & Configuration

Environment Variables

Variable	Default	Description
NVIDIA_API_KEY	(Required)	Your NVIDIA NIM API key.
PROXY_API_KEY	None	Optional key to protect the proxy itself.
STORAGE_ENGINE	sqlite	Persistence backend: redis, sqlite, or memory.
REDIS_URL	None	Required if STORAGE_ENGINE=redis (e.g., redis://localhost:6379).
PROXY_PORT	8788	Local port for the proxy.
RATE_LIMIT_RPM	0	Global rate limit (requests per minute). 0 to disable.

Quick Start

# Install the proxy
pip install nvd-claude-proxy[full]

# Export your API key
export NVIDIA_API_KEY=nvapi-...

# Run the proxy
ncp run

Then point your Claude Code at the proxy:

export ANTHROPIC_BASE_URL=http://localhost:8788
claude

🏗 Architecture

The proxy uses a Chain of Responsibility pattern for streaming events: MetadataProcessor -> TextProcessor -> ToolProcessor -> SafetyProcessor -> FinalizerProcessor

This ensures that even complex interleaved reasoning and parallel tool calls are correctly reconstructed for the Anthropic SDK.
