What it is

rvt-mcp is a local bridge between an MCP client and a running Revit session. A .NET 8 server talks MCP over stdio; a thin add-in per Revit year (2022–2027) runs inside Revit and is reached over localhost TCP (≤2024) or a named pipe (≥2025). Nothing leaves the machine, it is C# end to end, and lengths are millimetres at the tool boundary. Details: ARCHITECTURE.md.

Agents get a typed tool surface for common Revit work, a C# escape hatch for everything else, and an optional way to turn repeated patterns into personal tools (ToolBaker): start from a shared runtime and grow your tools on top. Family Editor authoring is out of scope for now.

Install

For users: let your AI agent do it. You don't need to run anything yourself. Copy the line below, paste it into your AI agent (Claude Code, Codex, Cursor, …) and go get a coffee while it does the job. The agent follows AGENTS.md and asks you before it installs anything or edits your client config.

Install rvt-mcp for me: https://github.com/bimwright/rvt-mcp

Or run the installer yourself. Close Revit, then in PowerShell:

$tag = (Invoke-RestMethod https://api.github.com/repos/bimwright/rvt-mcp/releases/latest).tag_name
$dir = "$env:TEMP\RvtMcp.Setup-$tag-win-x64"
Invoke-WebRequest "https://github.com/bimwright/rvt-mcp/releases/download/$tag/RvtMcp.Setup-$tag-win-x64.zip" -OutFile "$dir.zip"
Expand-Archive "$dir.zip" -DestinationPath $dir -Force
powershell -ExecutionPolicy Bypass -File "$dir\install.ps1"

One run sets up both sides: the add-in for every Revit 2022–2027 on the machine, and the rvt-mcp entry in every MCP client it finds (each config is backed up first). Add -WhatIf to preview, -Client claude,cursor to wire only those clients, or -Client none to skip client configs and register the server yourself — it lives at %LOCALAPPDATA%\Bimwright\rvt-mcp\server\current\rvt-mcp.exe (per-client steps).

Check it works: restart your AI client, open a model in Revit, start MCP from the ribbon (Add-Ins → RvtMcp) and ask the agent to call revit_get_current_view_info. It should return the active view's name and type.

Upgrade: run the new release's installer the same way — no uninstall first; clients only need a restart. Uninstall: uninstall.ps1 -Yes in the same folder removes the add-ins and the server (settings stay unless you add -Purge); run install.ps1 -Uninstall -Client auto first to also remove the client entries. More, including developer and NuGet installs: docs/install.md.

Claude Desktop MCPB (v1.0.0): the extension launches the separately installed gateway from the matching release. Use install.ps1 -Client none for this route to avoid a duplicate Desktop registration. See MCPB installation and settings.

Tools

Mode	Tools	Notes
Fresh install	233	install.ps1 seeds "toolsets": ["all"] in rvtmcp.config.json
Bare rvt-mcp.exe	46	query + create + view + meta
--toolsets all	233	Full catalog
all + adaptive bake	236	Adds 3 suggestion-lifecycle tools

Counts exclude your personal baked tools. The installer writes the seeded default only when rvtmcp.config.json doesn't already set toolsets — your own list survives upgrades, and removing the key (or setting your own CSV) returns a bare server to the 46-tool surface. Read-only filters individual tools by ReadOnly=true, including reads inside mixed toolsets. Tools that can write files are excluded even when their default output is inline.

Toolset	What it covers
query	View, selection, filters, stats, parameters, relationships, worksets, groups/assemblies
create	Grids, levels, rooms, line/point/surface-based elements, groups
view	Create views, sheets layout helpers, capture image, crop/scale
meta	Batch execute (max 20), multi-Revit targets, recent models, project info, purge unused (MVP), message, send_code
lint	View naming patterns, firm-profile detect, warnings summary
schedule	List/create schedules, fields, formulas, data
families	Load/unload, types, instances, audit, export .rfa (project-side)
modify	Operate/color elements, set parameters, change type, workset assign
delete	Delete by id
annotation	Tags, text, dimensions, regions, keynotes, checks
export	PDF/DWG/IFC/NWC helpers, room data, and related export tools
mep	Systems, connectors, networks, place terminals/fixtures, etc.
graphics	View filters, overrides, visibility/phase
toolbaker	list/run baked tools; suggestion tools only if adaptive on
sheets	Sheets, titleblocks, revisions, renumber, viewport layout

geometry	BBox, measure, clash, volume/area, …
rooms	Rooms/areas/spaces, finishes, separators
links	Revit/CAD links, coordinate audit, acquire/publish coordinates
parameters	Project/shared parameters
organization	Saved selections, view templates
workflows	Composite clash/audit/sheet/takeoff-style flows
structural	Columns, beams, foundations, rebar, loads, …

send_code, ToolBaker, ribbon and languages

• revit_send_code_to_revit (on by default) compiles and runs a C# body inside Revit when no typed tool fits; --read-only or --disable-send-code removes it. See docs/send-code.md, and docs/stairs-workflow.md for stairs.
• ToolBaker: revit_list_baked_tools / revit_run_baked_tool need --toolsets toolbaker. Adaptive bake (--enable-adaptive-bake, off by default) suggests tools from repeated calls; nothing is added until you accept one. Bake compiles inside Revit — no Visual Studio needed. See docs/bake.md.
• Ribbon: start or stop the connection, open History to search and re-run past calls, and switch completion Toasts (on by default).
• UI languages: the add-in UI comes in 15 languages and follows Revit's UI language; change it with the Language button in the ribbon slide-out — it opens Settings → General → Language (BIMWRIGHT_UI_LANGUAGE still wins). Tool names and payloads stay English. See docs/localization.md.

Why activity toasts exist

Toasts are work feedback, not just decoration. They grew out of three practical needs:

• Free users from watching the chat. In real-world MCP workflows, an AI agent can work for a long time while Revit gives little visible feedback. Watching the chat just to check whether the agent is doing anything wastes attention. The activity card reports completed tool calls so users can turn to other work between updates.
• Support multitasking. The maintainer develops and repeatedly tests several desktop applications in parallel. Compact notifications make it easier to follow those sessions without keeping every chat in view.
• Modernize the experience. Revit-side feedback makes automation feel more responsive and understandable, without interrupting work with modal dialogs.

A toast reports a tool result, not progress inside a running tool or completion of the entire task. Repeated results share one card; notifications may wait while Revit is minimized or blocked by a modal dialog. They do not replace reviewing the agent's work.

Each card names the gateway and Revit year (for example rvt-mcp 2022), the latest tool, and the Success · Failed · Capture counts. A capture preview stays on the card for at least 5 seconds.

Deliberate hover opens an activity timeline showing the newest three results, each with its local completion time (HH:mm:ss). Scroll up for earlier calls in that card. Incoming results follow the bottom with a short glide-in (the rows rise, the new row fades in and its outcome dot pops; none of this with reduced motion); while you read older calls, your position stays put. Click inside the timeline to read without closing it; clicking the rest of the card opens History. This works with branding off. Summaries are bounded and redacted, stay in memory only, and clear when the card closes. Script objects/arrays show counts; an incomplete survey remains explicitly incomplete. Server-local tools do not gain toast coverage from this UI change.

Notifications are on by default and can be turned off. In Settings → Toast, choose the idle duration (10/20/30/60 seconds; default 20) and Show branding (off by default), which shows the wordmark on hover. The choice applies immediately and is saved across Revit restarts; users do not need to display branding to get activity feedback.

Position: choose Horizontal alignment (Left/Right) and Vertical alignment (Top/Bottom) independently in Settings → Toast; the default is top-left. Changes apply to the open card and are saved immediately, and changing a corner clears any saved drag position. Turn on Allow dragging the card to move it by its title row; a plain click still opens History. Turning drag off keeps the saved position, turning it on restores it, and Reset position clears it. The position is stored relative to the Revit window and kept inside the monitor's work area. A card anchored at the bottom grows upward, and falls back to the other side when there is no room. Motion follows the Windows animation setting. A failed save is shown under the setting while the choice stays active for the session. Hovering the latest-tool line or a timeline row shows the sanitized result, Success/Failed, the completion time and the measured duration when available. Coordination between toasts of several Autodesk applications is not part of this.

Prompts

v1.0.0 provides six MCP prompts — pick /mcp__rvt-mcp__revit_<name> (Claude Code) or the prompts menu (Claude Desktop), and the agent follows the script with the tools it already has:

• revit_getting_started — orient in the open model (read-only, works on defaults).
• revit_drawing_layout — supply request: arrange the viewports of one sheet. Reads real sheet-space positions first (revit_get_viewport_geometry), agrees the alignment with you, shows a dry-run plan (revit_align_viewports), moves only after you confirm, then reads back. Needs query,sheets,view,meta. In read-only mode it reports and proposes only.
• revit_change — supply change: survey relationships, agree the smallest scope for this request, confirm the concrete proposal before writing, then read back and record the reason in the conversation. Needs query,meta; works without send_code. In read-only mode it stops at the survey/proposal. Missing or incomplete evidence stays "not checked"; readback is not a complete inventory of indirect changes, and the record is not a persistent change database.
• revit_model_audit — health audit: warnings, families, dry-run purge candidates (needs workflows,families,lint,meta).
• revit_pre_issue_check — checks resolved sheets before issue (needs sheets,view,annotation,lint,meta). Supply sheet numbers/IDs, an explicit number/name filter, or all; a named sheet set needs its member sheets. Sampled model warnings and incomplete checks are reported as NOT VERIFIED, not a sheet-level pass.
• revit_stairs — guided stair creation through send_code (writes only after your confirmation). Includes the transaction/failure/cleanup template; no source checkout is needed.

If a prompt's toolsets aren't enabled, it answers with the exact --toolsets line to add — nothing runs half-configured. Read-only protection stays on when the missing tools allow it; prompts requiring write-capable toolsets explain the conflict rather than silently changing configuration. Prompts are instructions for the agent, not server-enforced workflow locks.

---

Configuration

Since v1.0.0 the server reports _changes and local per-model _history. History defaults on independently of call logs; use --disable-change-history to disable recording. The meta tools revit_record_change, revit_get_change_records and revit_resolve_history_identity attach reasons to explicit call IDs, query stored changes and record the owner's history choice after a copy or Save As. See change tracking for privacy, limits and recovery.

revit_survey_change_impact is a tool in query: a bounded, read-only survey of ten relationship groups, including with send-code disabled. scopeThreshold is required for each request; view/schedule iteration is opt-in through maxViews > 0. Partial results remain explicit and parameter observations are not trusted history snapshots. See change-impact survey.

Permissions & auto mode

These controls arrive in v1.0.0. The v0.8.1 package does not include the new switches or per-tool read-only filtering. send_code and run_baked_tool must be called directly; batch_execute rejects them.

MCP annotations describe each tool's document/file effects. Transient selection, active-view and zoom changes count as read-only. send_code has no annotations: keep it out of automatic permissions and confirm each arbitrary-code call. For Claude Code, copy only the read-only allow list below; do not allow the broad mcp__rvt-mcp__* wildcard. The list covers --toolsets all; your selected toolsets may expose fewer tools.

send_code defaults on, independently of ToolBaker; call-log defaults off. CLI overrides environment variables, which override JSON. Authenticated server settings override plugin settings for that request only. Call-log off suppresses the server journal, plugin mcp-calls.jsonl and send-code body journal; in-memory History remains available. Body journaling needs both call-log on and its separate TTL opt-in. ToolBaker usage.jsonl is separate and follows adaptive-bake settings.

The response guard defaults on: UTF-8 warnings at 65536 bytes, strong warnings above 262144, a 716800-byte budget and a 1048576-byte transport cap. JSON escaping and MCP content/metadata are measured at the server. Oversized reads return RESPONSE_TOO_LARGE with narrowing guidance; completed writes return a compact summary. Arbitrary code output spills to a local file with mutation_applied: null; inspect the file instead of rerunning the command. A spill file is kept 36 hours by default (--spill-retention-hours, 1-8760; an invalid value uses 36) and no file-count cap deletes a younger file. Turning the guard off leaves the transport cap active. Byte limits must be integers >=1024, ordered warn <= strong <= budget <= max; adjust lower thresholds when lowering the budget.

Supported Revit versions

Revit	Plugin TFM	Transport
2022–2024	.NET Framework 4.8	TCP
2025–2026	.NET 8 (net8.0-windows7.0)	Named Pipe
2027	.NET 10 (net10.0-windows7.0)	Named Pipe

Full Revit desktop only; Revit Viewer is not a supported target. CI builds all six add-ins, but runtime depth varies by year — recheck baked tools and custom C# on the years you use.

Security and privacy

• Local by default: loopback TCP or a local named pipe, with a per-session auth token in the discovery files under %LOCALAPPDATA%\Bimwright\rvt-mcp\.
• Tool arguments are schema-checked before handlers run; errors returned to the model are sanitized.
• send_code runs arbitrary C# in the Revit process — powerful and risky. Use --read-only or --disable-send-code if that is unacceptable.
• Adaptive bake, body cache and send_code journals are opt-in and stay under your user profile; defaults do not write raw send_code bodies to long-lived logs.
