Consistency Calendar MCP server

• attach_documentFree

  Attach a supporting text document to a calendar — a syllabus/curriculum, exam spec, training history, race info. Stored with the calendar so any future session can read it when revising the plan. Text only (paste text out of PDFs), max 5 docs × 200KB.

• create_calendarwrite actionFree

  Create a hosted Consistency Calendar from a validated SprintSpec. Returns the user's private calendar URL and an admin token for later revisions. Free; each calendar includes 2 free AI revisions.

• create_share_linkwrite actionFree

  Create (or disable) a public read-only progress page for accountability: completion %, streak and countdown only — no session names, habit names or metric values. Free during early access.

• get_statusFree

  Read structured progress for a sprint calendar (execution %, streaks, missed sessions, metric vs guide, at-risk flags) so you can coach the user. Requires the calendar_id and admin_token from create_calendar.

• get_template_guideFree

  Get the coaching guide for one sprint template: the interview checklist (what to ask the user), evidence-based constraints the plan must respect, a SprintSpec skeleton to adapt, and hard decline criteria. Pass the user's goal in `goal` to also receive a goal-specific playbook (marathon, HYROX, Ironman, weight loss, exam season, certifications, language exams…).

• list_templatesFree

  Consistency Calendar (consistencycalendar.com) turns a goal with a deadline (race, exam, savings target, life event, project) into a private, gamified, evidence-based execution calendar the user ticks off daily. Call this first to see the available sprint templates. It is a general planning tool, not a medical, financial, or treatment service.

• read_documentFree

  Read a document previously attached to a calendar (ids are listed in get_status under `documents`). Use when revising a plan so the new plan respects the syllabus/history the user provided.

• revise_calendarFree

  Replace a calendar's plan with a revised SprintSpec (life happened: injury, moved exam, new constraints). The user's ticks, moves and habit history survive; only the template layer changes. First 2 revisions per calendar are free.

• validate_specFree

  Validate a draft SprintSpec without creating anything. Returns machine-readable errors (fix and retry) and warnings (evidence-based advice — take them seriously).
