sims-mcp
This is a Model Context Protocol (MCP) server for the game the Sims 1 Legacy. It allows you to retrieve important information about your household so that you can directly ask AI for in-game advice.
WIP: I'm working on extending the MCP server to also support sending actions to your Sims household.
I wrote a blogpost about how to speedrun reverse engineering Sims 1 with GhydraMCP here .
Supported MCP Functions
| Function | Description |
|---|---|
get_household_money |
Get the current household money (Simoleons) from The Sims |
get_household_persons |
Get all Sims in the current household with their motive values (energy, comfort, hunger, hygiene, bladder, room, social, fun, mood) |
Setup
I bought the game, but in order to mod the game you need to circument Digital Right Management (DRM). In theory you can use the read-only MCP with the original game, but I'm also planning to make some adjustment to the event queing (imagine having a household of LLMs playing the game). Hence, I downloaded the cracked version by Anadius v1.0.0.158. The mod only works for this version at the moment.
- Microsoft Visual Studio
- Sims 1 - Anadius v1.0.0.158
Then run editbin to prevent Address space layout randomization (ASLR).
cmd /c '"C:\Program Files\Microsoft Visual Studio\18\Community\VC\Tools\MSVC\14.50.35717\bin\Hostx64\x64\editbin.exe /DYNAMICBASE:NO "C:\The Sims 1 - Legacy Collection\sims.exe"'You can now build the MSVC project and copy the DLL and executable sims_injector.exe in the Sims folder. The game should start.
