AppLaunchFlow MCP

MCP server for AppLaunchFlow — create App Store & Google Play screenshots with AI.

Connect

AppLaunchFlow is a hosted MCP connector with OAuth 2.1 and PKCE. No API key,local token, or scoped npm package name is required.

Codex

The shortest setup command configures the hosted connector and opens OAuth:

npx -y applaunchflow connect codex

Useful follow-up commands:

npx -y applaunchflow status
npx -y applaunchflow disconnect

The equivalent native Codex commands are:

codex mcp add applaunchflow --url https://mcp.applaunchflow.com/mcp
codex mcp login applaunchflow
codex mcp get applaunchflow
codex mcp remove applaunchflow

ChatGPT

npx -y applaunchflow connect chatgpt

Paste the displayed URL when creating a custom MCP connector in ChatGPT. Thesame URL is also available at any time with npx -y applaunchflow url.

Other MCP clients

Use this Streamable HTTP endpoint and enable OAuth when prompted:

https://mcp.applaunchflow.com/mcp

Hosted service

The public Streamable HTTP service uses OAuth 2.1 authorization code flow withPKCE through the AppLaunchFlow dashboard.

npm ci
npm run build

npm run start:http

Public endpoints:

Health: https://mcp.applaunchflow.com/healthz

Official MCP Registry

AppLaunchFlow is published as io.github.ynnickw/applaunchflow in the officialMCP Registry. The checked-in server.json is the canonicalregistry manifest and points clients to the hosted OAuth connector.

Registry publication runs automatically from GitHub Actions when the manifestchanges on main. Keep the manifest version aligned with package.json; thetest suite enforces this before publication.

APPLAUNCHFLOW_MCP_PUBLIC_URL may be either the origin or the full /mcpURL; both services normalize it to the same canonical resource URL. SetAPPLAUNCHFLOW_MCP_PUBLIC_URL=https://mcp.applaunchflow.com/mcp andNEXT_PUBLIC_APP_URL=https://dashboard.applaunchflow.com on the dashboard.

The included Dockerfile produces a non-root OCI image for the hosted server.The MCP host and dashboard must both be served through public HTTPS inproduction. Do not expose the Node process directly without a TLS-terminatingplatform or reverse proxy.

Personalized style workflow

Screenshot and social-graphics styles are prepared once for the selected app screenshots, then the chosen style is applied from cache. This lets users compare styles without paying for another AI call when they choose one.

For App Store screenshots:

list_source_screenshots
prepare_screenshot_styles with 3-7 ordered paths
The personalized gallery opens automatically. Compare each template's V1/V2 render and confirm the choice; the gallery creates the new variant from cache and opens the editor.

browse_templates can reopen a prepared catalog, and apply_screenshot_styleremains available when an API client supplies a template id directly.

For social graphics:

list_source_screenshots
prepare_social_graphics_styles with 3-7 ordered paths
browse_social_templates with the returned templateIds, generationId, and catalogKey
apply_social_graphics_style with the returned catalogKey

The screenshot result includes phone, tablet, and desktop. The social result includes all six supported formats. generate_layouts and generate_graphics remain available for legacy direct single-template calls.

Development

npm ci
npm run dev

Run npm test before publishing or deploying. Seedocs/openai-submission.md for the final OpenAIsubmission checklist and manual test cases.
