export const deleteCategory = async ( id: string, ): Promise<Category | undefined> => { await db.read() const index = db.data.categories.findIndex((c) => c.id === id) if (index === -1) { return undefined } const deletedCategory = db.data.categories.splice(index, 1)[0] db.data.memos.forEach((memo) => { if (memo.categoryId === id) { memo.categoryId = undefined } }) await db.write() return deletedCategory } - src/server/tools.ts:246-270 (registration)Registers the 'deleteCategory' tool on the MCP server, defining its schema, description, and handler that wraps the repository function.
