What is AgentSEO?
AgentSEO gives teams and AI agents a way to work with SEO research and search visibility data through a developer-friendly API. It is designed for marketers, SEO practitioners, agencies, and developers who want to bring search research into their own applications and workflows instead of switching between separate tools for each task.
The product provides a REST API, a hosted Model Context Protocol (MCP) server, and client libraries for Node.js and Python. These interfaces let a developer or connected AI assistant request supported SEO data from a project or automation. AgentSEO focuses on practical research workflows such as keyword research, search engine results page (SERP) analysis, competitor research, rank tracking, content gap discovery, and visibility checks for AI-powered search experiences.
A team can use the API to gather search results for a topic, compare competing pages, find keyword opportunities, or connect ranking and visibility data to an internal dashboard. An agency can use it as a data layer within its own reporting or research process. Developers can connect the service to scripts, applications, and AI-agent workflows using the interface that fits their environment. The MCP server is intended for compatible AI clients, while the REST API and SDKs support direct integration from software.
AgentSEO is built for people who need structured search data that can be reused across workflows. Rather than presenting SEO as only a manual dashboard activity, it makes research capabilities available to software and agents through documented interfaces. Users should choose the relevant operation for their needs and review the returned data as part of their own analysis; search visibility changes over time and no tool can guarantee a specific ranking or business result.
AgentSEO offers a free entry tier alongside paid plans. Current plan limits and prices are listed on the official pricing page at agentseo.dev/pricing. Developers can review the documentation for API access, MCP setup, and SDK usage before integrating. Visit agentseo.dev to explore the product and documentation.
