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.
How do I connect an MCP server to an agent?
The entry lists how to run it (npx, uvx, docker or a remote URL) and the environment variables. A config snippet goes into the agent settings.
Do I need a key or a paid account?
It depends on the server. Each entry states the auth method and requirements, including paid accounts, in the limitations block.
