@connskill/mcp-growth-services

An MCP server that gives an AI agent (Claude Desktop, Cursor, OpenClaw, …) direct tools for CONNSKILL Growth Services — SEO & SERP data, SMS verification and social-marketing orders — paid per call via x402 (USDC on Base).

Tools are generated live from the service's own /openapi.json and /.well-known/x402. New endpoints show up automatically; nothing is hardcoded.

What you get

22 tools (generated live, so the count grows with the service), e.g. serp_report, keyword_metrics, ai_search_volume, google_trends, keyword_difficulty, domain_tech, backlinks_report, sms_order, smm_order, plus the free *_quote / *_services lookups. Each tool's description carries its price (e.g. "costs 0.15 USDC on Base via x402").

Payment model

• Free endpoints (quotes, catalogue, status) work with no wallet.

• Paid endpoints need X402_WALLET_KEY — the private key of a Base wallet holding USDC. x402-fetch signs an EIP-3009 authorization per call; the facilitator pays the gas. Without a key, paid tools return a clear hint instead of spending anything.

• X402_MAX_USD (default 1.00) caps what any single call may spend. Set it low (e.g. 0.50) — it is your safety belt against a runaway or buggy call.

⚠️ The wallet key can spend real USDC. Use a dedicated wallet funded with only what you want the agent to be able to spend, never your main wallet.

Setup

npm install        # in this folder

Claude Desktop / Cursor (mcpServers)

{
  "mcpServers": {
    "connskill-growth": {
      "command": "node",
      "args": ["/absolute/path/to/automaton/mcp/index.mjs"],
      "env": {
        "X402_WALLET_KEY": "<your Base wallet private key, 0x-prefixed>",
        "X402_MAX_USD": "0.50"
      }
    }
  }
}

Omit X402_WALLET_KEY to run in free-only mode (quotes and catalogue lookups).

Environment

Test

node test-smoke.mjs   # lists tools, calls a free endpoint, checks the paid guard

No key is used by the smoke test — it never spends.
