RimSage provides real source access and retrieval tools to maximize API reliability.

Query real C# and XML so your agent references APIs that actually exist.

Pull on demand to cut token usage and improve model performance.

Retrieval optimized for RimWorld's architecture.

Connect in seconds, available anywhere, start anytime.

Online service is the recommended default for new users.

Use the hosted MCP endpoint to start instantly.
