Model Context Protocol
An open protocol that gives AI models a standard way to connect to external tools and data sources; WebMCP brings the idea to websites.
The way AI agents interact with the web is undergoing a major shift. Instead of just reading text on a page, AI can now directly connect to external tools and data, thanks to an open standard called the Model Context Protocol, or MCP.
Traditionally, connecting an AI model to a specific tool required custom, bespoke code. MCP changes this by creating a universal interface. It allows an AI to instantly understand what a tool does and how to use it, simply by sharing a name, a description, and the required inputs.
This technology is now moving to the web through WebMCP. This allows websites to expose their own unique capabilities directly to AI agents. For example, instead of an AI assistant trying to guess its way through a complicated travel website, the site can expose a specific flight-booking tool with clear, defined fields.
For search engine optimization, this represents a massive transition. It means moving from content that is merely read by search engines to capabilities that can be directly called by AI. As AI agents become a main way people navigate the digital world, offering clean, structured tools will be just as important for visibility as traditional web pages.
The Model Context Protocol (MCP) is an open standard for connecting AI models to external tools and data through a consistent interface. Rather than every model and every tool needing bespoke glue, MCP defines a common way for a model to discover what a tool does and call it — name, description, input schema, and a result.
Its ideas carry directly into the web via WebMCP, which lets websites expose their own tools to AI agents. A site can declare, for example, a book_flight tool with the fields it needs, so an agent invokes a defined action instead of guessing its way through the page.
For AI SEO, MCP marks a shift from content that's read to capabilities that are called. As AI agents proliferate, exposing clean, structured tools becomes a new surface for visibility alongside traditional pages.
