Gpu Bridge Mcp Server is an MCP server that exposes 30 GPU-powered AI services (LLMs, image generation, audio, video, embeddings, reranking, PDF parsing, NSFW detection, and more) as Model Context Protocol tools. It integrates with the GPU-Bridge API and supports the x402 payment protocol, allowing autonomous AI agents to pay per request on-chain with USDC on Base L2 without API keys or accounts.
Install by adding a configuration entry to claude_desktop_config.json using npx -y @gpu-bridge/mcp-server and setting the GPUBRIDGE_API_KEY environment variable (or use x402 for keyless agent payments). Once configured, Claude Desktop can invoke services through the MCP tools: gpu_run, gpu_catalog, gpu_estimate, gpu_status, and gpu_balance.
Visit [gpubridge.xyz](https://gpubridge.xyz) and grab a free API key, or use the x402 protocol for keyless agent payments.
x402 is an open payment protocol that enables autonomous AI agents to pay for compute with USDC on Base L2. The agent receives an HTTP 402 Payment Required response, pays USDC (gas < $0.01, settles in 2 seconds), then retries with a payment proof to get the result.
It provides five tools: `gpu_run` (execute any service), `gpu_catalog` (list available services with pricing), `gpu_estimate` (estimate cost before running), `gpu_status` (check job status and results), and `gpu_balance` (check balance and spend).
Pricing starts from $0.003/1K tokens for LLMs, $0.01/image for image generation, $0.005/minute for speech-to-text, $0.005/1K chars for TTS, $0.0001/1K tokens for embeddings, $0.001/query for reranking, and $0.005/document for PDF parsing. All prices are in USD; x402 payments are in USDC on Base L2.
No, with the x402 protocol you can pay per request on-chain without any account or API key. Alternatively, you can use a free API key from gpubridge.xyz.
