Notes
- Machine-to-machine only. Human browsers receive a plain-text 402 by design.
- Status: closed private beta. Endpoints, pricing and datasets may change.
- Source of the gateway lives in a private repository; this repo hosts the public MCP documentation and registry manifest.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
