What this MCP does

Builds project schedules and Gantt charts from task dependencies, durations, milestones, float, and critical paths.

create_gantt

Create a Gantt chart from a task list — no account or API key needed. YOU author the plan: list the tasks in execution order with realistic working-day durations and dependencies (0-based positions of earlier tasks; use { task, type, lag } for start-to-start/finish-to-finish links or lag). Milestones have duration 0. Only add a dependency where a task truly needs another one finished - independent tasks should run in PARALLEL (share a predecessor, or take no dependencies at all and start at the project start). Group tasks into top-level phases for a structured plan/WBS: the phase task gets isPhase: true, its tasks get parent = the position of the phase. LoopGantt schedules it with its critical-path engine and returns a picture of the chart, the dates, the critical path and a link where the user can view, export (PNG/PDF) and save the chart. Always show the user the link. Tasks with a due date take deadline: YYYY-MM-DD (a marker - the reply reports the fit). Use create_gantt when the user wants a chart to open, export or save; use schedule_project instead for what-if date math where nothing should be stored.

Phases take no dependencies and no parent; their dates become the envelope of their tasks.'}, 'deadline': {'type': 'string', 'description': 'Finish-by date YYYY-MM-DD for a task with a due date (essay due, exam day, launch).

get_template

Get one industry template by slug: its task list with durations, ready to adapt and pass to create_gantt.

Input schema

{'type': 'object', 'required': ['slug'], 'properties': {'slug': {'type': 'string', 'description': 'Template slug from list_templates'}}}

list_templates

List LoopGantt's industry project templates with task counts and typical durations. Pick one, fetch it with get_template, adapt it, then create_gantt.

Input schema

{'type': 'object', 'properties': {}}

schedule_project

Compute a schedule without storing anything: dates, critical path, float and project end for a task list (same input shape as create_gantt; name optional). Use it to answer "what is the critical path?", "when would this finish?", "how much slack does X have?". Use create_gantt when the user wants a chart they can open.
