AI SEO Tools With an API or MCP Server

Every tool on this page states a public API, an SDK, an MCP server or a native connection to an AI assistant such as Claude, ChatGPT or Cursor on its own website. MCP, the Model Context Protocol, is a standard way for an AI agent to call a tool's data and actions directly, so an assistant can pull keyword data, run an audit or check rankings without someone copying results between windows.

An API matters when SEO data has to flow into your own dashboards, scripts or reports, or when an agency runs the same checks across many clients. Before you build on one, read the vendor's developer documentation: which plan includes access, which endpoints exist, and how usage is counted. The cards are ordered by the number of published guides that name each tool.
