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:

| Tool | What it does | |---|---| | create_flow | Create a new Flow2 presentation | | update_flow_meta | Rename or update flow-level metadata | | get_flow | Read the current state of a flow | | add_screen | Add a new screen to a flow | | get_screen | Read a screen and its blocks | | delete_screen | Remove a screen from a flow | | add_block | Add a block (text, image, button, etc.) to a screen | | patch_block | Update an existing block's content or styling | | delete_block | Remove a block from a screen | | get_blocks_schema | List available block types and their schemas | | get_preview | Get the screenshot URL for a single screen | | render-flow-preview | Show the whole flow inline in chat — vertical-scroll preview of all screens with theme-accent indicator (interactive on Apps-aware clients) | | render-screen-preview | Show a single screen inline in chat as a phone-framed screenshot | | list_jobs / check_job_status | Track long-running operations | | check_credits | Check the remaining credits on your account |

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:

Discovers /.well-known/oauth-authorization-server
Registers itself as a client via the registration_endpoint
Walks you through the standard authorization-code flow with PKCE
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.
