Stellaris Companion includes a local MCP bridge. MCP-capable desktop clients can use it to request campaign briefings and structured context while the Companion remains the source of truth.
Connection model
The AI client starts or connects to a local server configured by Stellaris Companion. When you ask a campaign question, the client calls an appropriate read-only tool, receives a focused briefing, and answers in its own conversation.
This is not a public web endpoint. Your campaign archive is not published to this website.
