GPU-Bridge MCP Server

30 GPU-powered AI services as MCP tools — LLMs, image generation, audio, video, embeddings, reranking, PDF parsing, NSFW detection & more. x402 native for autonomous AI agents: pay per request on-chain with USDC on Base L2. No API keys. No accounts.

What is GPU-Bridge?

GPU-Bridge is a unified GPU inference API with native x402 support — the open payment protocol that allows AI agents to autonomously pay for compute with USDC on Base L2. No API keys, no accounts, no human intervention required.

This MCP server exposes all 30 GPU-Bridge services as Model Context Protocol tools, giving Claude (and any MCP-compatible AI) direct access to GPU inference.

Install in Claude Desktop (2 minutes)

1. Get your API key (or use x402 for autonomous agents)

Visit gpubridge.io and grab a free API key, or use the x402 protocol for keyless agent payments.

2. Add to claude_desktop_config.json

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "gpu-bridge": {
      "command": "npx",
      "args": ["-y", "@gpu-bridge/mcp-server"],
      "env": {
        "GPUBRIDGE_API_KEY": "your_api_key_here"
      }
    }
  }
}

3. Restart Claude Desktop

That's it. Claude now has access to 30 GPU-powered AI services.

x402: For Autonomous AI Agents

GPU-Bridge supports the x402 payment protocol, enabling truly autonomous AI agents to pay for compute without human intervention.

Agent Request → GPU-Bridge returns HTTP 402 Payment Required
      ↓
Agent pays USDC on Base L2 (gas < $0.01, settles in 2s)
      ↓
Agent retries with payment proof → GPU-Bridge executes and returns result

Python Example with x402

from x402.client import PaymentClient

client = PaymentClient(private_key="0x...", chain="base")

response = client.request(
    "POST",
    "https://api.gpubridge.io/v1/run",
    json={
        "service": "flux-schnell",
        "input": {"prompt": "A robot painting on a canvas", "steps": 4}
    }
)
print(response.json())

Pricing

All prices in USD. x402 payments in USDC on Base L2.
