Frequently asked questions
What is an MCP server?
An MCP server connects an agent to external data and tools over a single protocol: files, databases, APIs and services. The agent calls its tools while it works.

Do I need a key or a paid account?
It depends on the server. Each card states the auth method and requirements, including paid accounts, in the limitations block.
