MCP Server for Ultimate Brain

An MCP server for managing Thomas Frank's Ultimate Brain Notion system. Provides 30 workflow-oriented tools for Tasks, Projects, Notes, Tags, and Goals using the PARA methodology, plus a daily_review_snapshot consolidator that returns everything a daily review needs in one call.

Setup

1. Create a Notion integration and share your Ultimate Brain databases with it.

2. Run the setup command for your client. It will auto-discover your data sources from Notion and write the config file.

Claude Code

# Project scope (writes .mcp.json in current directory)
uvx --from ultimate-brain-mcp ultimate-brain-setup --client claude-code --scope project

# User scope (writes ~/.claude.json)
uvx --from ultimate-brain-mcp ultimate-brain-setup --client claude-code --scope user

Claude Desktop

uvx --from ultimate-brain-mcp ultimate-brain-setup --client claude-desktop

You can also pass your Notion secret via environment variable to skip the prompt:

NOTION_INTEGRATION_SECRET=secret_... uvx --from ultimate-brain-mcp ultimate-brain-setup --client claude-code --scope project

Tools

Tasks (6)

• search_tasks — Filter by name, status, project, priority, due date (due_on for a single day), My Day, labels, parent task, completion date
• create_task — Create with name, status, due, priority, project, labels, tag_ids, location
• update_task — Patch any task properties (incl. tag_ids and location)
• complete_task — Mark done with recurrence handling
• get_my_day — My Day tasks sorted by priority
• get_inbox_tasks — Unprocessed tasks needing triage

Projects (4)

• search_projects — Filter by status, tag
• get_project_detail — Properties + task breakdown + recent notes
• create_project — Create with name, status, deadline, tag, goal
• update_project — Patch project properties

Notes (4)

• search_notes — Filter by type, project, tag, favorite, date
• get_note_content — Properties + page body as plain text
• create_note — Create with type, project, tags, URL
• update_note — Patch note properties

Tags (3)

• search_tags — Filter by PARA type
• create_tag — Create with name, type, parent
• update_tag — Patch tag properties

Goals (4)

• search_goals — Filter by status
• get_goal_detail — Properties + linked projects
• create_goal — Create with name, status, deadline
• update_goal — Patch goal properties

Cross-Cutting (3)

• daily_summary — My Day, overdue, inbox, active projects/goals (counts only)
• archive_item — Archive any UB item
• set_page_content — Replace or append page body content (markdown → blocks)

Workflow Consolidators (2)

• daily_review_snapshot — One call returns current time + IANA timezone, all five daily-review buckets (completed today, overdue or due today, due tomorrow, on My Day, inbox), the deduplicated outstanding union, project + area-tag lookup tables, and the live Tasks schema (Location property type, valid options, Labels options). Replaces ~7 separate read calls.
• bulk_update_tasks — Apply multiple task patches concurrently with per-row results. Never raises on a single failure — surfaces each failed row through the results list so the caller can retry or skip.

Generic (4)

• query_database — Query any secondary database
• get_page — Fetch any page by ID
• get_page_content — Page properties plus body as plain text
• update_page — Update any page properties

Set these in .env (or pass via the MCP client config):

Var	Required	Purpose

UB_TASKS_DS_ID, UB_PROJECTS_DS_ID, UB_NOTES_DS_ID, UB_TAGS_DS_ID, UB_GOALS_DS_ID	yes	Primary data source IDs
UB_TIMEZONE	optional	IANA name (e.g. Europe/London). Used by daily_review_snapshot to resolve now/today/tomorrow. Falls back to TZ, then UTC.
UB_*_DS_ID (Work Sessions, Books, etc.)	optional	Secondary data sources surfaced via query_database
