Complete reference for all 76 MCP tools
The civ6-mcp server exposes 76 tools through the Model Context Protocol. Each tool is available to any MCP-compatible AI client.
Tools are organized into three categories based on their behavior:
| Category | Count | Description |
|---|---|---|
| Query | 34 | Read-only inspection of game state |
| Actions | 34 | Commands that modify game state |
| System | 8 | Game lifecycle and turn management |
Conventions
- Required parameters are marked with a red asterisk (*)
- Optional parameters show their default value
- Read-only tools are safe to call at any time without side effects
- Action tools modify the game (move units, set production, etc.)
- Destructive tools can significantly alter game state (end turn, load saves)
Parameter types
All parameters use simple types:
| Type | Description |
|---|---|
string | Text value |
integer | Whole number |
number | Decimal number |
boolean | true or false |
