Stitch MCP — Create Project

Creates a new Stitch project. A project is a container that holds one or more generated screens. You need a projectId before you can call generate_screen_from_text.

Critical prerequisite

Only use this skill when the user explicitly mentions "Stitch" in their request. Never trigger Stitch operations silently during regular conversation.

When to use

• Starting a new design task or app concept
• The user says "create a Stitch project", "start a new project in Stitch", "design X using Stitch"
• You need a projectId before calling generate_screen_from_text
• Starting work in a new domain (keep related screens in one project)

Step 1: Extract a meaningful title

Infer a descriptive project title from the user's request:

User says	→ title
"Design a pet adoption app"	"PawPals" or "Pet Adoption App"
"Make a login page"	"Login Page"
"SaaS dashboard for analytics"	"Analytics Dashboard"
"E-commerce product listing"	"Product Listing"

If no clear name is evident, use a descriptive label: "Design Project [date]".

Step 2: Call the MCP tool

{
  "name": "create_project",
  "arguments": {
    "title": "[Descriptive project title]"
  }
}

Step 3: Extract and store the project ID — CRITICAL

The tool returns a name field in the format projects/NUMERIC_ID. You must extract the numeric portion:

Tool response:

{
  "name": "projects/3780309359108792857",
  "title": "Analytics Dashboard",
  "createTime": "2026-03-24T14:30:00Z",
  "visibility": "PRIVATE",
  "deviceType": "DESKTOP",
  "projectType": "TEXT_TO_UI",
  "designTheme": {
    "colorMode": "LIGHT",
    "customColor": "",
    "colorVariant": "TONAL_SPOT",
    "roundness": "ROUND_TWELVE",
    "spacingScale": 1,
    "headlineFont": "INTER",
    "bodyFont": "INTER",
    "labelFont": "INTER",
    "namedColors": {},
    "designMd": ""
  }
}

The designTheme populates with full values (including designMd and namedColors) after the first screen is generated. For a brand-new project, expect mostly empty/default theme values.

Extract:

• Full name: projects/3780309359108792857 → use for list_screens, get_project
• Numeric ID: 3780309359108792857 → use for generate_screen_from_text, get_screen

Store both values. Announce to the user:

"Created project 'Analytics Dashboard' (ID: 3780309359108792857). Ready to generate screens."

ID format rules (critical — different tools need different formats)

Tool	ID format required
generate_screen_from_text	Numeric only: 3780309359108792857
get_screen	Numeric only: 3780309359108792857
list_screens	Full path: projects/3780309359108792857
get_project	Full path: projects/3780309359108792857

Integration

After creating a project, the next step is always stitch-mcp-generate-screen-from-text to generate the first screen.
