Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@hermes-architectural-mcp Check this plan PDF for dimension accuracy and export IFC"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
An open-source, Docker-first MCP service that converts existing architectural plans into dimension-verified millimetre geometry, IFC models, and consistent CPU-rendered views for Hermes Studio.
The service separates visual interpretation from deterministic geometry. It will not export IFC or render a project until its explicit PlanSpec passes boundary, expected-area, containment, and overlap checks.
PDF dimensions are treated as candidates only. Exact geometry must be represented in millimetres and validated. This prevents a 100 m2 plan from being presented as a visually enlarged but dimensionally unsupported design.

inspect vector or raster PDF plans and render a review preview;
detect dimension text candidates without trusting them automatically;
validate site boundaries, spaces, total area, containment, and overlaps;
reject visual-only geometry and boundaries resized merely to match a stated area;
export validated walls as IFC using IfcOpenShell;
queue CPU Blender render jobs so long renders do not hold the MCP connection open;
persist source files, reports, IFC, .blend, and PNG outputs;
expose internal download URLs so Hermes can copy deliverables into its workspace;
expose tools through MCP Streamable HTTP at /mcp.
This is an early engineering release. It does not replace architectural, structural, life-safety, accessibility, or local-code review by licensed professionals.
The provided compose.yaml joins an existing external Docker network named proxy and does not publish a host port.
Create or update a Dockhand stack using compose.yaml.
Confirm the proxy network already exists.
Deploy the stack.
From another container on proxy, verify:
curl http://architectural-mcp:8000/healthIn Hermes Studio, add an HTTP MCP server with:
http://architectural-mcp:8000/mcpImport hermes-skill/SKILL.md as a Hermes skill.
The container stores projects in the named volume architectural_projects.
The MCP tool accepts base64 PDFs, but local files are more efficiently uploaded over the internal Docker network:
curl --fail --silent --show-error \
-H 'Content-Type: application/pdf' \
--data-binary '@/workspace/plan.pdf' \
'http://architectural-mcp:8000/api/projects/my-project/plan-pdf'No upload route is published to the host in the supplied stack.
