Dm MCP server

dm-mcp

MCP Server for DreamMaker/BYOND Development

An MCP (Model Context Protocol) server that provides AI coding assistants with full access to DreamMaker language tooling. Works with Claude, Cursor, Windsurf, Continue, and any MCP-compatible client.

Features

Code Intelligence

Parse & Navigate - Load .dme projects, explore type hierarchies, search symbols
Type Checking - Real-time diagnostics via SpacemanDMM's dreamchecker
Go to Definition - Find where any type, proc, or variable is defined

Compilation & Runtime

Compile - Build projects with the DM compiler
Run/Stop - Control DreamDaemon instances
Topic Calls - Send Topic() messages to running servers

Map Tools

Map Info - Get dimensions, z-levels, area statistics
Find on Map - Search for object instances across maps
Render Maps - Generate PNG previews of .dmm files

Protocol Support

Full BYOND client protocol implementation (for testing)
RUNSUB encryption for secure packet handling

Installation

Prerequisites

Rust 1.70+
BYOND (for compilation and runtime features)

Build from Source

git clone https://github.com/imcynic/dm-mcp.git
cd dm-mcp
cargo build --release

The binary will be at target/release/dm-mcp.

Configure Your MCP Client

Claude Code / Cursor / Windsurf

Add to your MCP settings (usually ~/.config/claude/mcp.json or IDE settings):

{
  "mcpServers": {
    "dm-mcp": {
      "command": "/path/to/dm-mcp"
    }
  }
}

Continue

Add to ~/.continue/config.json:

{
  "experimental": {
    "modelContextProtocolServers": [
      {
        "name": "dm-mcp",
        "transport": {
          "type": "stdio",
          "command": "/path/to/dm-mcp"
        }
      }
    ]
  }
}

Available Tools

Tool	Description
`dm_parse_environment`	Parse a `.dme` file and cache the object tree
`dm_get_type`	Get type info (vars, procs, parent, children)
`dm_get_proc`	Get proc details (params, location, docs)
`dm_get_var`	Get variable info (type, initial value)
`dm_list_types`	List types with optional path prefix filter
`dm_search_symbols`	Search for types, procs, or vars by pattern
`dm_check_errors`	Run type checker, get diagnostics
`dm_get_definition`	Find source location of any symbol
`dm_compile`	Compile the project
`dm_render_map`	Render a map to PNG
`dm_map_info`	Get map dimensions and statistics
`dm_find_on_map`	Find instances of a type on a map
`dm_run`	Start DreamDaemon with a `.dmb` file
`dm_stop`	Stop the running game
`dm_status`	Get game server status
`dm_topic`	Send a Topic() call to the server
`dm_connect_test`	Test BYOND client protocol

Example Usage

Once configured, you can ask your AI assistant things like:

"Parse /code/myss13/myss13.dme and show me the type hierarchy for /mob/living"

"Find all instances of /obj/machinery/door on the station map"

"Check for type errors in the codebase"

"Compile the project and run it on port 1337"

How It Works

dm-mcp uses SpacemanDMM for parsing and type checking. This is the same tooling used by the SS13 community for linting and IDE support.

The server communicates over stdio using JSON-RPC, following the MCP specification.

Platform Support

Windows - Full support (BYOND native)
Linux - Full support (requires BYOND Linux build)
macOS - Untested but should work with BYOND Wine wrapper

BYOND Paths

The server looks for BYOND in these locations:

Windows:

C:\Program Files (x86)\BYOND\bin\
C:\Program Files\BYOND\bin\

Linux:

/usr/local/byond/bin/
/opt/byond/bin/
System PATH (dm, DreamMaker, dreamdaemon, DreamDaemon)

Development

# Run with debug logging
RUST_LOG=dm_mcp=debug cargo run

# Run tests
cargo test

# Build release
cargo build --release
