LC Mods MCP server

A remote MCP server for GTA mods. It searches the LC Mods catalogue: 140,000+ mods for GTA San Andreas, Vice City, GTA III, GTA IV and GTA V (PC). For each mod it says how to install it with LC Mod Installer, a free Windows program that installs a mod into the game in one step and can take it out again.

Endpoint: https://libertycity.net/agent/mcp (Streamable HTTP, no key, read-only)
MCP Registry: net.libertycity/mods
Plain-text guide for agents: https://libertycity.net/llms.txt

Tools

Tool	What it does
`search_mods`	Search mods by words, with filters for game, category and "installs automatically". Sorted by relevance, popularity or date. Each result has a description, picture, size, install count and rating.
`mod_info`	One mod: versions, variants, size, whether it needs LC Engine, how to install it.
`collections`	Ready mod sets for a goal (graphics, realism, real cars, low-end PC), installed one by one.
`how_to_install`	Steps to get LC Mod Installer (signed setup, silent install) and the command `LCModsInstaller.exe agent install <id>`.

The server only finds mods and explains how to install them. Installation itself runs on the user's Windows PC through LC Mod Installer. The program is also a local MCP server (LCModsInstaller.exe mcp) with tools that install, remove and check mods.
