Seamcult is an early-access garment pattern design editor built to work with AI agents through MCP. An agent drafts and revises pattern pieces on a canvas; Seamcult supplies drafting rules, a mannequin built from body measurements, and audits that check pattern geometry and fit-related measurements.

Designers can review work on the canvas, give changes in words or by drawing over pieces, and export patterns as PDF, PLT, or DXF. The page presents workflows for drafting from a photo or text brief, adapting a pattern to a new body, and reworking an existing pattern.

Key Features

MCP agent drafting

Connect an agent that speaks MCP so it can draw and revise garment pattern pieces on the Seamcult canvas. The page names Claude Code, Cursor, and ChatGPT as examples.

Canvas review and feedback

Review pattern pieces on the canvas, mark an area, and tell the agent what to change in words or by drawing over the pieces.

Measurement-based mannequin

Build a body model from measurements for drafting and checking fit against the planned ease.

Pattern audits

Run checks intended to find pattern mistakes and help the agent fix them. The page notes that the audits are not yet exhaustive.

Pattern export

Export patterns as PDF, PLT, or DXF, with options for roll or standard paper sizes and pattern outlines with or without allowances.

Draft from a text brief

Describe a garment, review the agent's draft on the canvas, and request refinements.

Rework an existing pattern

Give an agent a pattern and instructions for changes; it redraws the pieces on the canvas and Seamcult checks them.

Integrations

MCP-compatible agents

Connect agents that speak MCP to draft and revise patterns. The page names Claude Code, Cursor, and ChatGPT.
