Using Notch with Claude & other AI assistants

Notch has an MCP server, so AI assistants like Claude can work in your drawings with you: list your drawings, read markups and takeoffs, place markups and measurements, answer comments and export PDFs. The assistant acts as you — it sees exactly what you can see in Notch, and nothing else.

Connect Claude#

1. In Notch, open Workspace settings → API & MCP.
2. Click Connect to Claude. Claude opens with Notch filled in.
3. Click Add, then Connect, and sign in to Notch when asked.

Or, in Claude, open Settings → Connectors → Add custom connector and paste https://notch.build/api/mcp.

Other assistants#

Any MCP client that supports remote servers with sign-in can connect. Use the server URL https://notch.build/api/mcp and sign in to Notch when prompted.

What the assistant can do#

• Read — workspaces, projects, drawings and pages, markups, measurements, layers, tags, comments, share links and connected cloud drives.
• Create and edit — markups, measurements, page scales, layers, custom columns, comments, tags, overlays and exports.
• Delete or overwrite — deleting markups, measurements, layers, comments and tags; revoking share links; publishing your markups back over the source file in your cloud drive. Your assistant should ask you before any of these.

Every tool is labelled as read-only, editing or destructive, so assistants like Claude know when to check with you first.

Disconnect#

Remove Notch under Claude's Settings → Connectors, or revoke the session in Notch under Workspace settings → API & MCP → Active sessions.
