Gantt chart SaaS with server-side critical path and dependency-aware shift-impact tools, plus CRUD.
Scored across 15 tools
Each tool targets a distinct resource-action pair, such as create_task vs update_task vs set_task_progress. Even the two task-modifying tools have clearly separated concerns: one updates arbitrary fields, the other specifically updates progress with auto-derived status.
All tool names follow the verb_noun snake_case pattern (create_, list_, delete_, get_, add_, set_, update_). The only compound verb, reschedule_and_propagate, still fits the pattern and reads predictably.
15 tools is within the well-scoped 3-15 range, and each tool covers a meaningful operation for a project management domain. No redundant or trivial tools are present.
Tasks have full CRUD plus progress and dependency management, but milestones lack update/delete operations, and dependencies only support addition (no removal). These are notable gaps that may require workarounds in some workflows.
Add a finish-to-start dependency between two tasks in the same project.
Inputs: successorId (required), predecessorId (required), lagDays.
Add a milestone (key date) to a project.
Inputs: date (required), name (required), projectId (required), color.
Create a new project in a workspace. Returns the created project. Subject to plan-based project count limits.
Inputs: name (required), workspaceId (required), color, endDate, +2 more.
Create a new task in a project. Dates must be in YYYY-MM-DD format. End date is exclusive (a 1-day task has end = start + 1 day).
Inputs: name (required), endDate (required), projectId (required), startDate (required), +6 more.
Permanently delete a project. All tasks, milestones, and dependencies inside the project are also removed. This cannot be undone.
Inputs: projectId (required).
Delete a task. Child tasks and dependencies are removed as well.
Inputs: taskId (required).
Calculate the critical path of a project on the Ganty side and return it as data (don't ask the model to reason over raw task lists). Uses forward/backward CPM with progress-aware remaining duration. Returns critical_path tasks in order, per-task earliest/latest start/finish + slack, project_end_date, and total_duration_days. v1 limitations: Finish-to-Start dependencies only (Ganty has no other types), calendar days by default (business_days=true skips Sat/Sun but no holiday table), ignores multi-period segments, no resource calendars. Returns { error: 'cyclic_dependency', cycle } if a cycle is detected.
Inputs: project_id (required), as_of_date, business_days.
Get detailed information about a single task, including assignees and dependencies.
Inputs: taskId (required).
List milestones in a project (key dates such as launch or review gates).
Inputs: projectId (required).
List all projects in a workspace (excluding archived).
Inputs: workspaceId (required).
List tasks in a project. Supports optional filtering by name (search), status, and assignee.
Inputs: projectId (required), search, status, assigneeId.
Get all workspaces the authenticated user is a member of.
Inputs: no named parameters.
Compute the downstream impact of shifting a single task. Default is dry_run (no DB writes); set mode='commit' to actually persist the changes. Cascades forward only (no pull): successors are pushed only if their predecessor's new end + lag would violate their current start. Tasks with progress=100 are treated as pinned; pass pinned_task_ids for additional pins. When a pin would be violated, the change is recorded in 'conflicts' and not propagated further. In mode='commit', if any conflicts exist nothing is written (all-or-nothing transaction). Same v1 limitations as get_critical_path: FS only, calendar days by default, no holiday table, ignores multi-period segments.
Inputs: task_id (required), mode, shift, business_days, +3 more.
Update the progress percentage of a task (0-100). Status is auto-derived: 0=not_started, 1-99=in_progress, 100=done.
Inputs: taskId (required), progress (required).
Update fields of an existing task. Only provided fields will be modified.
Inputs: taskId (required), name, color, status, +5 more.
