BIMLynx

Talk to your construction project. A remote MCP server that connects Claude to Autodesk Construction Cloud / Forma.

What your team can do in plain language

Browse hubs, projects, folders, and model versions
Create, update, and pin construction issues — directly onto 3D elements
Read clash detection results and route them to the right discipline
Compare design versions: what was added, removed, moved, or changed
Quantity take-offs by level and category from the full BIM parameter set

See it working

Claude answering total floor area by level from a live ACC model, as a table of 14 levels totalling 6,751 m² — Quantity take-off from the model's full Revit parameter set — 203 floor elements across 14 levels, totalled, with the unit system verified rather than assumed.

A design version diff between v3 and v4, grouped into a table by Revit category with added, removed and modified counts — Version diff, grouped by category: what was added, removed, moved or changed between two model versions — the signal for routing a change to the discipline it affects.

A dry-run preview of creating an issue, showing the exact request body and asking for confirmation before creating it — Every write is previewed first. The dry-run shows the exact request that would be sent, then stops — nothing reaches the project until you confirm.

Audit chain verified valid for the day, listing the last five logged actions including a preview followed by an executed create — And the log proves what ran. Note the `preview` → `executed` pair: the approval step is recorded, not just displayed.

Safety first

Every write is previewed first — nothing mutates without an explicit, payload-bound approval
Hash-chained, per-tenant audit log of every action
One dedicated Autodesk service account per customer (Autodesk's official tenant-isolation pattern for ISVs) — your data is scoped by your own project membership, never a shared credential
Credentials encrypted at rest; bearer keys stored only as hashes

How it connects

Paste the endpoint into your MCP client (Claude Desktop, VS Code) with the bearer key we issue for your organization:

https://mcp.bimlynx.com/mcp

Get access

BIMLynx is free to use. Write to hello@bimlynx.com and we issue a bearer key for your organization — onboarding is two short steps in your admin console (add our Client ID, invite the robot account), no developer skills needed.

The key on its own reaches nothing: our robot account only sees the projects your admin invites it into, and your admin can cut that access in ACC at any time — no need to ask us. Prefer to run everything yourself? The server is open source and self-hosts with your own Autodesk credentials.
