Glasshouse MCP

Use Glasshouse from Claude Desktop, Cowork, and Claude Code.

This is a remote MCP server that lets an AI assistant read and write your Glasshouse BIM journal — projects, entries, relations, BIM property definitions. Once installed you can ask Claude things like "list my open projects" or "add this product as a Construction child of that Building element" and it will call the Glasshouse API on your behalf.

You'll need an active Glasshouse account and your personal API key.

Install in Claude Desktop

1. Get your API key

Sign in to app.glasshousebim.com/profile and copy the value under API-key. Keep it secret — it gives full read + write access to everything your Glasshouse account can see.

2. Add the connector (OAuth — recommended)

  1. Open Claude Desktop → Settings → Connectors.
  2. Click Add custom connector.
  3. URL: https://mcp.glasshouse.app/mcp
  4. Click Connect. Your browser opens on the Glasshouse connect page — paste your API key from step 1 and click Authorize. The browser closes and Claude Desktop is now wired up. Your key never leaves your machine as-is; it's encrypted into a short-lived OAuth token.

Prefer to skip the browser step? Add a custom Authorization: Bearer YOUR_KEY_HERE header on the connector instead — the server accepts both.

3. Try it

In a new chat (Claude Desktop or Cowork), ask:

List my Glasshouse projects.

If Claude comes back with your project list, you're wired up.

Install in Claude Code

From a terminal:

claude mcp add glasshouse --scope user -- \
  npx -y mcp-remote https://mcp.glasshouse.app/mcp \
  --header "Authorization: Bearer YOUR_KEY_HERE"

What Claude can do with this

Twenty-five tools — ten reads, thirteen writes, and two targeted deletes. Claude can list projects, discover a project's schema, search and read journal entries with their relations, create new entries, add and update relations, delete individual relations, author BIM property definitions and Property Sets, manage saved journal views (columns + filters), and run pre-configured automations (bulk operations + data-quality tests). Everything is scoped to your Glasshouse account — Claude can only see and change what you can already see and change.
