Network Data Bridge (MCP)

Ask questions about your transport network from an AI chat app on your PC: "which lines lose money?", "which vehicles are past their lifespan and what could replace them?", "which big towns have no rail service?". The app answers with live numbers from your game. Fun to try: plan your next routes and cargo chains together. The app knows where every town is and how big it is, so you can ask "which big towns near each other have no line yet?" "which steel mill is starved of coal, and where is the nearest mine?" or "sketch a regional rail network for the north of the map, starting with the busiest links", then build the best ideas yourself. The gallery shows an example: a long-term rail plan drawn from a save's live data. This mod only shares your game's data. It adds no AI-generated content to the game and changes nothing: no building, buying or selling. It works with any AI app that supports the Model Context Protocol (MCP). What the app can see: - lines: stops and their towns, vehicles, capacity usage, 12-month profit, profit per vehicle, running costs and problems - vehicles: model, age against lifespan, maintenance, load, running cost, value and profit; live position, speed and state, with checks for bunched lines and stuck vehicles - industries: location, level, inputs delivered and outputs produced and shipped per year, missing inputs and closures, plus supply and demand per cargo - stations: passengers and cargo waiting now, long waits, how full they are and the lines stopping there; your depots - towns: location, population, size per district, goods each district needs, public transport reach and the lines serving them - finances: balance, loan, earnings, company value and the finance table per carrier - vehicle models you can buy this year: price, capacity, top speed, power and lifespan SETUP (Windows PC only; on consoles the mod switches itself off. Needs Python 3.8+ and an AI app with MCP support): 1. Enable this mod for your save. It can be added to an existing save and removed again. 2. Get the companion MCP server (one Python file, no extra packages) by pasting this into PowerShell: $d="$env:LOCALAPPDATA\tf3-mcp"; mkdir $d -Force >$null; iwr https://github.com/bsaurusrex/tf3-network-data-bridge/releases/latest/download/tf3_mcp_server.py -OutFile "$d\tf3_mcp_server.py"; py "$d\tf3_mcp_server.py" --setup It downloads the server from the GitHub release below and adds it to supported AI apps automatically. For other apps it prints the settings to paste into the app's MCP configuration. 3. Restart your AI app, load your save and ask away. Full guide, manual setup and troubleshooting: https://github.com/bsaurusrex/tf3-network-data-bridge How it works: the MCP server asks the game for data whenever your AI app needs it, through small files in the game's user data folder, and the mod answers with live numbers. Between requests the mod does nothing. It makes no network connections; your AI app handles the conversation as usual. Work is spread over frames, so it does not cause stutter, even on large maps. Settings: CPU time per frame, town list on or off, and logging.
