What is an MCP Server? How to Connect One to Your Docs

Model Context Protocol (MCP) is a standard introduced by Anthropic that lets AI agents connect to external systems such as APIs, databases, documentation, code hosts, and messaging platforms through discoverable tools with defined schemas. Unlike traditional APIs, which require callers to already understand available endpoints and parameters, MCP enables agents to inspect capabilities, search for relevant information, and execute actions through a consistent request-response process. For API documentation, an MCP server can expose OpenAPI-based tools for listing and searching endpoints, retrieving endpoint details, and making live requests, allowing assistants to access current documentation selectively rather than relying on stale exports or training data. The approach can improve developer workflows, reduce documentation-related support requests, and provide more accurate API guidance, while authentication can separately control access to documentation and live API calls. Building such a server independently requires ongoing engineering for protocol support, search, synchronization, and authentication, whereas ReadMe offers a managed option that generates an MCP server from an existing API specification, supports endpoint controls and custom tools, forwards user credentials for API requests, and provides analytics on agent usage.
