## What it does

This server exposes tabletop utilities to your agent over a remote HTTP endpoint. The available toolset covers hex-based grid generation, random dice rolling, encounter calculations for systems like D&D 5e and Pathfinder 1e, and procedural tables. It also includes analysis tools for chess engines and state trackers for Twilight Imperium.

The setup relies on the SSE protocol and connects to the hosted endpoint at `https://tools.moddable.games/mcp`. You do not need to install local runtimes or compile engine source files on your machine.

Because execution happens entirely on the remote host, the server fails immediately if the machine loses outbound internet access.

## Requirements
- Remote server: `https://tools.moddable.games/mcp`

## When to use it
- build hexagonal map layouts directly through prompts
- balance tabletop encounters for D&D 5e or Pathfinder 1e
- simulate dice rolls for board game mechanics
- evaluate positions across custom chess variants

## Example prompts
- Generate a hex grid layout for a 4-player territory game
- Build a balanced encounter for four level 3 characters in D&D 5e
- Roll 3d6 and pick a random faction for Twilight Imperium
