What is MCP (Model Context Protocol)?
MCP is an open protocol that lets an AI model or agent connect to external tools and data sources through a standard interface, instead of a one-off custom integration per tool.
Model Context Protocol (MCP) defines a standard way for an AI application to discover and call external "tools" — for example, reading a file, querying a database, or hitting an API — without the model provider or agent framework needing bespoke code for every integration.
Before MCP, connecting an agent to a new tool usually meant writing custom glue code for that specific combination. An MCP server exposes its capabilities in a standard shape, so any MCP-compatible agent can use it with the same client code.

OpenClaw agents connect to external tools through its skills system, which can call webhooks, APIs, or MCP servers depending on the integration — see the integrations pages for specific tools like n8n, Notion, and GitHub.
