AGS MCP Server

Model Context Protocol (MCP) server for Adventure Game Studio (AGS) compiled room (.crm) file manipulation.

Bridge tool that gives AI access to binary AGS room data for complete AI-powered adventure game development.

🎯 Project Vision

AI tools excel at reading and writing AGS script files (text), but cannot directly access compiled room (.crm) files. This creates a gap where developers must manually connect AI-generated scripts to room elements through the AGS editor.

The AGS MCP Server bridges this gap by providing programmatic access to binary .crm data, enabling AI to:

Connect script functions to hotspots, objects, and interactive elements
Read room layouts and interactive areas for context
Complete the full development workflow without manual AGS editor intervention

Core Workflow:

AI analyzes game requirements and room context
AI writes script functions (text files)
AI uses MCP server to connect functions to room elements in binary .crm files
Complete game ready for testing - no manual hookup required

🎮 AI Automation Examples

Room Analysis Workflow

AI → read_room_data → analyze layout → get_room_hotspots → identify missing interactions

Interactive Object Creation

AI: "Make the door interactive"
MCP: add_hotspot_interaction(door, "Look", "door_Look") 
AI: Generated function: door_Look() { player.Say("A sturdy wooden door."); }

Batch Room Processing

# AI processes multiple rooms for consistency
for room in ["room001.crm", "room002.crm", "room003.crm"]:
    hotspots = mcp_call("get_room_hotspots", {"roomFile": room})
    # Add missing interactions automatically
    for hotspot in hotspots:
        if "Look" not in hotspot["interactions"]:
            mcp_call("add_hotspot_interaction", {...})

🏗️ AGS Room File Format

The MCP server works with AGS's binary .crm (compiled room) format:

Block Structure

Block ID	Name	Description
1	Main	Room backgrounds, objects, masks
2	TextScript	Text script source (legacy)
5	ObjNames	Object and hotspot names
6	AnimBg	Animated backgrounds
7	CompScript3	Current compiled script
8	Properties	Custom properties
9	ObjectScNames	Script names for objects

Hotspot System

Detection: Bitmap mask where pixel colors = hotspot IDs
Interactions: Event-driven system (Look, Interact, UseInv, etc.)
Script Linking: Functions named hotspot{id}_{event} (e.g., hotspot1_Look)
Runtime Resolution: Dynamic function resolution from compiled scripts

🗺️ Development Roadmap

🎯 Mission: Complete AI-AGS Bridge

Enable AI tools to fully manipulate AGS room files without manual AGS editor intervention.

✅ Phase 1: Foundation (COMPLETE)

AGS tools compilation (crmpak, crm2ash)
MCP server architecture
.crm file reading/parsing implementation
Basic hotspot manipulation tools
Cross-platform support (Windows, macOS, Linux)
Proof-of-concept demo and documentation

✅ Phase 2: Enhanced Hotspot Operations (COMPLETE - READ-ONLY)

Goal: Complete hotspot script-to-binary connection capabilities

Advanced hotspot property modification (placeholder/read-only)

🚨 Troubleshooting

Common Issues

npx command not found:

# Make sure Node.js is installed
node --version

# If needed, install or update npm
npm install -g npm

Permission issues with npx:

# On Linux/macOS, you might need to use sudo
sudo npx ags-mcp-server

# Or fix npm permissions
https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally

MCP connection failed:

# Check stdio configuration and tool responses
echo '{"jsonrpc":"2.0","method":"tools/list","id":1}' | npx ags-mcp-server

File access errors:

# Make sure you're using absolute file paths or paths relative to your current directory
# Not paths relative to the MCP server installation
