How do I install MS Procject?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does MS Procject need an API key?

No required environment variable is listed on this record.

What transport does MS Procject use?

MS Procject runs locally over stdio.

When was MS Procject last checked?

Known Limitations

COM proxy staleness: When multiple projects are open, switching projects invalidates existing COM references. Always call switch_project before operating on a different file.
Undo stack: undo_last supports up to 10 consecutive undos. MS Project's COM undo is less reliable than the UI's.
File locking: Only one process can hold the COM connection. Don't open MS Project's GUI dialogs while the server is active.
Timezone-aware dates: COM may return timezone-aware datetimes. The server normalizes these via _to_naive() for safe comparisons.
Recurring tasks: MS Project's RecurringTaskInsert is a dialog-only COM method. The add_recurring_task tool simulates recurrence by creating individual occurrences under a summary task. Requires python-dateutil.
Timephased data: get_timephased_data can be slow on large date ranges. Keep queries to reasonable periods (weeks/months, not years).

Tests

# Run all phases
python tests/test_new_tools.py  # 11 tests (core CRUD)
python tests/test_phase2.py     # 10 tests (resources, baselines, WBS)
python tests/test_phase3.py     # 15 tests (custom fields, calendars, scheduling)
python tests/test_phase4.py     # 23 tests (advanced ops, multi-project, filtering)
python tests/test_phase5.py     # 11 tests (bug fixes, cost/work tracking)
python tests/test_phase6.py     # 75 tests (timephased data, calendar mgmt, variance)
python tests/test_phase7.py     # 57 tests (critical path intelligence, what-if)

202 tests total across 7 test suites. All tests require MS Project to be running (they create and close temporary projects).

Architecture

Single-file server (server.py, ~5,200 lines) using the FastMCP framework. All COM calls go through get_app() / get_proj() helpers. Dates are normalized with _to_naive() and formatted with _fmt_date().

Development Phases

Phase	Tools	Focus
1–2	25	Core CRUD, dependencies, resources
3	44	Custom fields, calendars, scheduling analysis
4	65	Advanced operations, multi-project, filtering
5	79	Bug fixes, cost/work tracking
6	96	Timephased data, calendar management, resource availability, variance reporting
7	99	Critical path intelligence: ordered sequence, period filtering, what-if analysis
