Implementation Reference
- src/index.ts:830-858 (handler)The handler function for the 'list_projects' tool. It scans a specified directory (default: ~/Documents) for RPG Maker MZ projects by checking for the presence of 'Game.rpgproject' files and returns a list of matching project directories.
case "list_projects": { const searchDir = (args?.directory as string) || path.join(process.env.HOME!, "Documents"); const entries = await fs.readdir(searchDir, { withFileTypes: true }); const projects = []; for (const entry of entries) { if (entry.isDirectory()) { const projectFile = path.join(searchDir, entry.name, "Game.rpgproject"); try { await fs.access(projectFile); projects.push({ name: entry.name, path: path.join(searchDir, entry.name), }); } catch { // Not an RPG Maker project } } } return { content: [ { type: "text", text: JSON.stringify(projects, null, 2), }, ], }; } - src/index.ts:82-93 (schema)The input schema definition for the 'list_projects' tool, specifying an optional 'directory' parameter.
name: "list_projects", description: "List all RPG Maker MZ projects in a directory", inputSchema: { type: "object", properties: { directory: { type: "string", description: "Directory path to search for projects (defaults to ~/Documents)", }, }, }, }, - src/index.ts:78-822 (registration)Registration of the 'list_projects' tool in the ListTools response handler, making it discoverable by MCP clients.
