SEO Authority MCP

Give AI agents typed SEO authority, keyword, competitor, content, audit, and internal-link tools backed by seo.forgemesh.io. Authority scores use open Common Crawl graph data. The server does not invent search volume, CPC, live SERP positions, complete backlinks, or Google metrics.

Install

npx -y @forgemeshlabs/seo-authority-mcp

Claude Desktop

Challenge-only mode—safe default, never spends:

{
  "mcpServers": {
    "seo-authority": {
      "command": "npx",
      "args": ["-y", "@forgemeshlabs/seo-authority-mcp"]
    }
  }
}

Automatic x402 settlement:

{
  "mcpServers": {
    "seo-authority": {
      "command": "npx",
      "args": ["-y", "@forgemeshlabs/seo-authority-mcp"],
      "env": {
        "SEO_X402_PRIVATE_KEY": "YOUR_DEDICATED_LOW_BALANCE_WALLET_KEY"
      }
    }
  }
}

Use a dedicated low-balance wallet. Never commit its private key.

Tools

Paid tools use exact USDC settlement on Base. Without SEO_X402_PRIVATE_KEY, each tool returns price, network, receiver, and retry guidance instead of spending.

Docker

docker build -t seo-authority-mcp:0.1.3 .
docker run --rm -i --read-only --cap-drop=ALL seo-authority-mcp:0.1.3

For automatic payment, pass the private key at runtime using your secret manager. Do not bake it into the image.

Environment

Variable	Required	Default	Purpose
`SEO_X402_PRIVATE_KEY`	No	unset	Enables automatic payment
`X402_MAX_PRICE_USD`	No	`0.15`	Per-call payment ceiling; can only LOWER the built-in cap
`X402_SESSION_BUDGET_USD`	No	`10`	Cumulative per-process ceiling; can only LOWER the built-in cap

The backend is fixed to https://seo.forgemesh.io. The server refuses to sign for any payee other than the ForgeMesh SEO wallet, any network other than Base mainnet, any asset other than USDC, or any amount over the cap. Requests are same-origin, time-limited (60s), size-capped (2 MB) and never follow redirects. Tool arguments are validated before any network call. Use a dedicated, low-balance wallet.
