MCP (tool integration)

MCP (Model Context Protocol) is an open protocol created by Anthropic that enables AI agents (such as Claude or Claude Code) to connect with external tools, databases, and APIs without building custom integrations. An MCP server exposes tools, resources, and prompts that the agent can use during a session. MCP functions as a standardized interface for AI systems: it lets you plug any tool into an AI agent, just like USB lets you plug any device into a computer.

For SEO workflows, MCP simplifys tool integration. For example, an MCP server for knowledge graphs provides graph access, while Ahrefs MCP delivers SEO data, and Notion MCP connects to your notes. Instead of writing an API wrapper for each tool, you install an MCP server and the agent instantly gains new capabilities.

Once a knowledge graph MCP server is installed, the AI agent can execute Cypher queries, create nodes, and analyze the knowledge graph without writing integration code.

In practice, start with existing MCP servers available through npm or pip, and build custom ones only when needed. This approach reduces development overhead while expanding agent capabilities.
