MCP Server

An MCP server known to Nautobot. Registering one records that the server exists, how to reach it, and what it advertises. It does not make anything callable: this app is a registry, and the apps that read it decide what to do with what they find here.

An MCP server carries no URL and no credential of its own. Both live on the External Integration it points at, which is also where the TLS settings and the timeout come from.

Fields an operator owns

Field	Type	Description
name	string	What this server is called in Nautobot. Unique. Not the name the server reports for itself.
description	string	What the server is for, in an operator's words.
external_integration	foreign key	The endpoint URL, its headers and TLS settings, and its secrets group. Required.
transport	choice	streamable-http, sse (deprecated), or stdio. Discovery reads a streamable-http server only. It skips the other two and says so, because a stdio server is a subprocess of its client and this app speaks no SSE. Register their tools by hand.
enabled	boolean	Whether the server is in service. A disabled server is skipped by discovery and is meant to be skipped by any app reading this registry.
tenant	foreign key	The tenant this server belongs to, if the deployment is divided that way. Optional.
tags	tags	Standard Nautobot tags.

Fields the discovery job owns

Every field below is written by MCP Server Discovery and is read-only over the REST API. All of it is self-reported by the server and none of it is verified.

Field	Type	Description
protocol_version	string	The MCP protocol revision the last discovery negotiated.
server_name	string	The name the server reports for itself.
server_version	string	The version the server reports for itself.
instructions	text	The server's own guidance on how to use it.
capabilities	JSON	The capabilities object the server advertised, stored whole.
last_discovered_at	datetime	When the tool list was last read successfully. Left alone when a run fails, so a stale server is visible.
