@gosniffy/mcp

Model Context Protocol server for the Sniffy ASO API. Exposes three tools over stdio: sniffy_quote, sniffy_diagnose, sniffy_sample. Drop-in for Claude Desktop, Cursor, and any other MCP-capable agent.

Install

# One-off (no install)
npx @gosniffy/mcp

Tools

| Tool | Cost | What it does | |------|------|--------------| | sniffy_sample | Free | Returns a canned fixture report. Use to demo the shape without a wallet. | | sniffy_quote | Free | Returns a quote with shallowScan preview + pricing.estimatedTotal. Use BEFORE sniffy_diagnose. | | sniffy_diagnose | PAID | Full ASO diagnosis. Auto-pays from SNIFFY_PRIVATE_KEY over x402 on Morph Hoodi. |

Every tool description includes a testnet-only warning. Agents should refuse to run with a mainnet key.

Claude Desktop config

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "sniffy": {
      "command": "npx",
      "args": ["-y", "@gosniffy/mcp"],
      "env": {
        "SNIFFY_PRIVATE_KEY": "0x..."
      }
    }
  }
}

Restart Claude Desktop. The three sniffy_* tools become available.

Cursor config

Same shape — drop the snippet under mcpServers in your .cursor/mcp.json (or per-project .mcp/config.json depending on Cursor version).

Environment

| Var | Required for | Default | |-----|--------------|---------| | SNIFFY_PRIVATE_KEY | sniffy_diagnose | — (tool returns payment_required error if unset) | | SNIFFY_BASE_URL | All tools | https://api.sniffy.io |

Testnet only. Sniffy settles on Morph Hoodi (eip155:2910) using HoodiTestToken. Never paste a mainnet private key. Get testnet funds at the Morph Hoodi faucet.
