x402-video MCP server

Give any MCP-capable agent (Claude Code, Claude Desktop, Cursor, ...) the ability to generate AI videos and pay per call — USDC on Base over the x402 protocol. No accounts, no API keys, no credit cards.

quote_price → generate_video (pays exact USDC quote, gasless) → get_job → video_url

Backed by x402video.com: ~$0.45 for a 5s 720p clip, custom 4–15s up to 1080p with optional audio ($0.13–$4.62). Prompts are screened before payment — rejected requests are never charged.

Tools

| Tool | Cost | What | |---|---|---| | list_skus | free | Live catalog + current USD prices | | get_stats | free | Public reliability stats (success rate, p50 generation time) | | quote_price | free | Exact USDC quote for a request, without paying | | generate_video | paid | Quote → spend-guard check → pay → job_id | | get_job | free | Poll status; returns video_url on success (24h link) |

Setup

You need a dedicated spending wallet with a few USDC on Base (8453). Never use your main wallet — see the 5-minute getting-started guide.

Claude Code

claude mcp add x402-video \
  --env BUYER_PRIVATE_KEY=0xYOUR_SPENDING_WALLET_KEY \
  -- npx -y x402-video-mcp

Claude Desktop / Cursor (JSON)

{
  "mcpServers": {
    "x402-video": {
      "command": "npx",
      "args": ["-y", "x402-video-mcp"],
      "env": {
        "BUYER_PRIVATE_KEY": "0xYOUR_SPENDING_WALLET_KEY"
      }
    }
  }
}

Without BUYER_PRIVATE_KEY the free tools (catalog, quotes, job polling) still work; only generate_video requires the wallet.

Environment variables

| Var | Default | | |---|---|---| | BUYER_PRIVATE_KEY | — | Spending wallet key (USDC on Base). Required only for generate_video. | | MAX_USD_PER_CALL | 5 | Hard spend guard — generate_video refuses quotes above this. | | GATEWAY_URL | https://api.x402video.com | Point at another gateway instance. |

How payment works

1. The tool POSTs your request unpaid; the gateway answers HTTP 402 with the exact USDC amount for that request (a free quote).
2. If the quote is within MAX_USD_PER_CALL, the request is retried with an x402 payment header — an EIP-3009 signature, so the buyer pays no gas.
3. You get a job_id; generation takes ~2 minutes (p50). Poll get_job, download video_url within 24h.
