# Microsoft To Do plugin Connects Claude to Microsoft To Do via the Microsoft Graph API. This is the plugin (`.plugin`) packaging of the same MCP stdio server shipped as the `ms-todo.mcpb` Claude Desktop extension — one codebase, two install formats. ## Install Upload `ms-todo.plugin` in the plugin picker. Then ask Claude to run `todo_login` once — a browser window opens for Microsoft sign-in. The refresh token is cached at `~/.ms-todo/token-cache.json` (shared with the Desktop-extension install, so you only ever sign in once per machine). ## Requirements - Node.js >= 18 on PATH (the server is a Node stdio process). - A Microsoft work account in the PESCO tenant. Auth is delegated (auth-code + PKCE); scopes: Tasks.ReadWrite, User.Read. ## Configuration Environment is baked into `.mcp.json` (client + tenant id). Optional overrides: | Variable | Purpose | | ------------------ | -------------------------------------------------------- | | `TODO_TOKEN_CACHE` | Alternate token cache path | | `TODO_TIMEZONE` | Zone for due/start/reminder dates (default UTC) | | `TODO_READONLY` | "true" registers only the viewing tools | ## Tools 17 tools: `todo_login/logout/test`, list CRUD (`todo_list_lists/create_list/ update_list/delete_list`), task CRUD (`todo_list_tasks/get_task/create_task/ update_task/complete_task/delete_task`), checklist items (`todo_list_checklist/ add_checklist_item/check_checklist_item/delete_checklist_item`).
