Safety notes✓Todoist MCP Server can create, update, delete, complete, reopen, reorder, archive, and bulk-modify tasks, subtasks, projects, sections, labels, comments, reminders, filters, shared labels, and collaboration state. Bulk create, bulk update, bulk delete, bulk complete, project deletion, section deletion, label deletion, reminder changes, and duplicate merge operations can alter many Todoist records at once. Dry-run mode simulates mutation operations but still queries real Todoist data for validation. Pro and Business features such as reminders, filters, shared labels, collaboration, backups, and workspace operations may expose or modify team data. Require confirmation before deleting tasks or projects, changing due dates in bulk, completing groups of tasks, modifying shared projects, creating reminders, downloading backups, or changing collaboration state.✓Trello MCP Server can create, read, update, move, archive, and delete board data depending on token permissions and requested tools. Card, checklist, label, due-date, start-date, comment, attachment, board, list, workspace, and active-board changes can affect real team workflows. File attachments are added from URLs; review source URLs and destination cards before allowing an agent to attach files. Use `TRELLO_ALLOWED_WORKSPACES` to limit workspace access, especially when a token can see personal, client, or production boards. Require confirmation before creating boards, adding attachments, deleting or archiving cards, changing due dates, moving cards between lists, or posting comments on behalf of a user.✓Time MCP Server can provide current time values and convert times between timezones. Incorrect timezone assumptions can cause missed meetings, bad deadlines, broken cron schedules, or confusing customer communications. Require human review before using generated time conversions for travel, incident response, legal deadlines, medication timing, billing, payroll, or production scheduling. Use the local timezone override when the runtime environment timezone differs from the user's expected working timezone.
Privacy notes✓Todoist API tokens, task IDs, project IDs, section IDs, label IDs, reminder IDs, comment IDs, user IDs, collaborator details, activity logs, completed tasks, backups, and productivity statistics can be exposed to the MCP client. Task names, descriptions, comments, due dates, deadlines, labels, reminders, attachments, project notes, and completed-task history can contain private work or personal planning data. Bulk and filter tools may reveal larger slices of a Todoist workspace than a single-task request. Backup download tools can expose a broad historical snapshot of Todoist data. Keep Todoist tokens in local MCP configuration only, and avoid sharing MCP logs, dry-run traces, or transcripts that include private task or project data.✓Trello API keys, tokens, board IDs, workspace IDs, card IDs, member names, labels, comments, checklists, attachments, due dates, and activity logs can be exposed to the MCP client. Active board and workspace selections may persist locally in Trello MCP configuration. Card descriptions, comments, attachments, and activity histories can contain private customer, roadmap, incident, or operational data. Proxy settings, Trello credentials, and workspace allowlists should be kept out of shared MCP configs, logs, screenshots, and transcripts. Response previews reduce some large card-description exposure, but full-card and activity tools can still return sensitive Trello content.✓Timezone names and local timezone detection can reveal approximate location, travel patterns, work region, or operational context. Time conversion prompts, meeting times, schedule details, target regions, and tool arguments may be visible to the MCP client and model provider. Avoid using sensitive calendar, travel, incident, or personnel timing data unless it is approved for the current model session.
Prerequisites
  • Todoist API token from Todoist integrations developer settings.
  • Node.js 18 or newer for the npm stdio server.
  • Review of whether the token has access to personal, shared, Pro, Business, or workspace features.
  • Optional `DRYRUN=true` for simulating mutation tools while still validating against real Todoist data.
  • Trello API key and token with access to the boards and workspaces Claude may use.
  • Bun-compatible published package runtime or an MCP client that can launch the packaged stdio server through npx.
  • Optional `TRELLO_BOARD_ID` or `TRELLO_WORKSPACE_ID` when a default board or workspace should be selected at startup.
  • Optional `TRELLO_ALLOWED_WORKSPACES` to constrain the token to specific approved Trello workspaces.
  • Python 3.10 or newer available to the MCP client runtime.
  • uvx available for package execution.
  • IANA timezone names for any timezone you want Claude to query or convert.
  • Optional local timezone override if system timezone detection is not desired.
