forgemeshlabs/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.

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.
