# rpgmaker-mv-mcp

Lets your assistant read and change an RPG Maker MV game: database, maps, events. Useful when a batch of edits would take hours in the editor.

## What it does

It speaks Model Context Protocol and plugs into Claude, Claude Desktop, Cursor and other MCP clients. The tool set covers all 12 database types — actors, classes, skills, items, weapons, armors, enemies, troops, states, animations, tilesets and common events — through one CRUD interface. Skill builders go further: give a name and a damage formula, get an editor-valid entry.

Maps work the same way. You can create a map, add or edit events, push a batch of commands, and build dialogue that splits into message boxes on its own. `render_map_image` produces a PNG with the actual tileset art, event sprites and an optional grid, so the model checks its own work instead of guessing. `connect_maps` wires transfer doors between two maps in both directions, and `list_map_connections` reports one-way doors and unreachable maps. Bulk balancing runs through `bulk_update_records` with a dry-run diff first; `simulate_battle` tests troops against the party using the real formulas.

Node.js 18+ is required. Each file gets a snapshot in `.mcp-backups/` before its first change of the session, `restore_backup` undoes anything, and `validate_project` flags broken references. Pass `--project` with the game folder at launch, or call `set_project` later.

## When to use it
- generate a damage skill from a formula
- track down every event that mentions a given NPC
- paint water and walls across a map in one pass
- rescale weapon attack with a diff before applying
- export all game text to CSV and load it back

## Example prompts
- Create a Fireball skill: magic damage, `a.mat * 4 - b.mdf * 2`, 12 MP, fire element.
- Find every event on every map that mentions the mayor.
- Link the castle map and the dungeon with two-way transfers.
