COMMUNITY (FREE) AND PRO

Horizun Revit MCP: what's free and what Pro adds

The MCP connects your AI agent to Revit 2023–2027 on Windows. The public Community edition is free and open source (Apache-2.0). Pro includes everything in Community and adds AI-ready templates, audits Community doesn't have, finish walls and modeling craft, and sheet tools.

Pro is installed from Horizun Suite with a paid (Pro) account. You need Revit and an MCP-compatible AI agent (for example Claude Desktop), paid separately.

All 125 Community tools are in Pro, which adds 22 and extends 22. The product also ships two experimental point-cloud tools that are not part of the offer. The two marked “being fixed” don’t count either until they are verified. Counted from each edition's inventory (Community as published on GitHub on 2 November 2026; Pro 5.0.1). In both, every write is rehearsed first and read back from the model; what Python reports is the script's own account.

WHAT PRO GETS DONE

Four jobs Community doesn't do.

House modeled by the agent in Revit with an AI-ready template: walls, door, windows and a hip roof.

Model to your standard

With an AI-ready template, the agent reads the template kit (conventions, types, rules and steps), picks each type from the catalog instead of inventing it, and closes with the kit's checks.

Support audit of level 2 in the Autodesk Snowdon Towers sample model: ten fixtures and equipment with nothing underneath, marked in red and numbered, with their id, category, type and gap in millimetres.

Check before you deliver

Finds unsupported floating elements, loose beam ends, rooms without floors, unconnected MEP connectors and isolated runs, with each element's id so you can fix it.

Sheet with the level 2 floor plan and reflected ceiling plan aligned by grid at the same scale, built by the agent in the Autodesk Snowdon Towers sample model.

Lay out sheets to the millimetre

Places and aligns viewports in paper millimetres, sets their scale, crops views to rooms or elements and won't let through viewports that don't fit on the sheet.

Walls and levels with craft

Models architectural walls as finish layers over the linked structural core, without overlaps. Splits walls, columns and risers at every level they cross, recreates doors and windows and reconnects the networks.

THE 22 TOOLS ONLY IN PRO

Tool by tool.

Six-step path on the HZ-000 start sheet of the structural AI-ready template: what the agent reads from the kit.

AI-ready templates

horizun_template_kit: reads the template kit (conventions, types, rules, clearances and steps) so the agent picks catalog types and closes with the kit's checks.

Level 2 plan with the ten unsupported elements the audit marked in red and numbered, in the Autodesk Snowdon Towers sample model.

Audit and verification

horizun_audit_support: unsupported elements, loose beams, rooms without floors.
horizun_audit_mep_connectivity: unconnected connectors and isolated runs.
horizun_room_boundaries: real boundaries and redundant rooms.
horizun_selection_context, horizun_query_relations, horizun_measure_geometry, horizun_query_family_internals and horizun_api_help.

Modeling craft

horizun_split_by_level, horizun_join_geometry, horizun_wall_finish, horizun_wall_sweep.
horizun_place_joinery_from_cad: doors and windows from DWG tags.
horizun_mep_fittings, horizun_plumbing_fixtures, horizun_family_reload, horizun_manage_classification_table.

Level 2 reflected ceiling plan on the sheet the agent built, with grids and scale, in the Autodesk Snowdon Towers sample model.

Sheets and views

horizun_sheet_layout, horizun_view_crop, horizun_view_visibility and horizun_planimetry_ops.

Being fixed, outside the offer and the count of 22. They ship in the product, but we don't sell them until they are verified on a real model:

horizun_room_finishes (being fixed): the per-room finish floor fails when applied.
horizun_coordination_view (being fixed): the color per linked model doesn't show in the view.

Pro also extends 22 tools both editions share: for example, sheet annotation goes from 7 to 19 operations, planimetry queries from 6 to 15 and change verification from 3 to 8.

Frequently asked questions

Is the free edition good for real work?

Yes. It has 125 tools to query, run general model audits, model from DWG and IFC, coordinate, take off quantities, produce sheets and export, plus Python inside Revit.

How do I install Pro?

From Horizun Suite, on 64-bit Windows 10 or 11, with a paid (Pro) Horizun Hub account.

What do I pay for separately?

Your Revit 2023–2027 license and the MCP-compatible AI agent you use, for example Claude Desktop.
