What's an MCP server?

Model Context Protocol servers expose tool catalogs to your agents — GitHub, Linear, Postgres, Brave Search, anything that speaks MCP.
Model Context Protocol (MCP) is an open standard for letting an AI host call tools that live in a separate process. Avery NXR hosts the client side: you point us at an MCP server (a local command or a remote HTTPS endpoint), we run the handshake, and the server's tool catalog shows up in the agent builder palette under the `mcp.<server>.<tool>` namespace. Your agents can then call those tools the same way they call built-in capabilities like `email.send`. The connection is local — outbound traffic flows directly from your device to the server you configured; Avery's central service is never in the path.
