Flow2

Flow2 MCP Server

Design mobile-first presentations - create, edit, preview, and publish from your AI assistant.

This is the official Model Context Protocol server for Flow2. It lets AI assistants like Claude work with your Flow2 account directly: spin up new flows, add and edit screens, drop in blocks, preview the result, and publish — all from a chat prompt.

• Endpoint: https://mcp.flow2.co/
• Transport: streamable-http
• Auth: OAuth 2.1 with Dynamic Client Registration (RFC 7591)
• Registry: co.flow2/flow2

Quick start

Claude Code (and Cowork)

claude mcp add --transport http flow2 https://mcp.flow2.co/ --scope user

Then run /mcp inside Claude Code to complete the OAuth sign-in.

Claude.ai (web + desktop)

Settings → Connectors → Add custom connector → URL: https://mcp.flow2.co/. Click Connect to authorize.

Cursor

In ~/.cursor/mcp.json:

{  "mcpServers": {    "flow2": {      "url": "https://mcp.flow2.co/"    }  }}

Other MCP-compatible clients

Any client that supports remote streamable-HTTP MCP servers can connect using the URL above. OAuth is handled automatically when the client supports DCR.

What it can do

The Flow2 MCP server exposes the full flow-authoring surface as tools:

All write tools are annotated with destructiveHint: false where appropriate so AI clients can reason about safety. Read-only tools are marked readOnlyHint: true.

Inline previews (Apps-aware clients)

On clients that support the MCP Apps extension (Claude.ai web + desktop, Claude Code, ChatGPT, Cursor, VS Code), render-flow-preview and render-screen-preview produce an interactive inline preview rendered inside a sandboxed iframe — no need to leave the chat to see your flow. CTA buttons on individual screens become click-through links; the indicator picks up the flow's theme accent color. Other clients fall back to the cover screenshot.

Example prompts

Once the server is connected, try:

• "Create a new mobile pitch deck for my fintech app called 'Lumen'."
• "Add a hero screen with a bold headline and a 'Get started' button."
• "Generate three product-feature screens with icons and short captions."
• "Show me my latest flow." (renders the inline preview)
• "Preview screen 3 of my pricing flow."
• "Share the link to my latest flow."

The assistant will call the right MCP tools, and you'll see the changes reflected in your Flow2 account in real time.

Authentication

The server implements OAuth 2.1 with Dynamic Client Registration. When you connect from a new client, it:

1. Discovers /.well-known/oauth-authorization-server
2. Registers itself as a client via the registration_endpoint
3. Walks you through the standard authorization-code flow with PKCE
4. Stores a refresh token for ongoing access

You can revoke a client at any time from your Flow2 account settings.

Privacy & data handling

• Scope: the MCP server only accesses Flow2 data belonging to the authenticated user.
• Logging: request metadata (tool name, timestamp, status) is logged for operational purposes; tool argument and response bodies are not retained beyond the request lifecycle.
• Third-party services: Flow2 uses a small set of infrastructure providers (hosting, error tracking) — see the Privacy Policy for the full list.
• Retention: authentication tokens are stored encrypted at rest; revoking access from your Flow2 settings purges them.
