SEOmatic MCP and Similarweb MCP, Compared
The Short Answer
The Similarweb MCP is Similarweb's official hosted MCP server. It gives an AI agent Similarweb's traffic estimates and competitive data for any website, and it does not change your website. SEOmatic's MCP server (https://app.seomatic.ai/api/mcp) is built for a different job. It reads your own Google Search Console data for free, audits your site, and can stage the fix in your CMS (18 platforms), wait for your approval, then measure whether the change worked. Pick the Similarweb MCP when you need traffic estimates for competitors' websites, which no Search Console can give you. Pick SEOmatic when you want your own site's real clicks from Search Console, not estimates, and an agent that fixes what they show.

Or use both. MCP servers sit side by side in the same agent. Ask Similarweb for its data, then ask SEOmatic to check your own Search Console and stage the fix.
