flutterflow-mcp

flutterflow-mcp

MCP server for the FlutterFlow Project API. Enables AI-assisted FlutterFlow development through Claude and other MCP-compatible clients.

What This MCP Does Best

This MCP excels at reading, exploring, and understanding your FlutterFlow projects. Here's what it's great at:

• Project exploration — Browse your projects, pages, components, and file structure
• Understanding functionality — Get clear summaries of what a page or component does, including its widget tree, actions, parameters, and state
• Tracing usage — Find everywhere a component is used, or every navigation action that leads to a page
• Inspecting configuration — View theme settings, API endpoints, data models, custom code, app state, integrations, and more
• Searching — Search project files by keyword, prefix, or regex to find exactly what you need
• YAML reference — Built-in documentation for FlutterFlow's YAML schema, so your AI assistant can understand and generate valid YAML
• Guided editing — A workflow guide (get_editing_guide) that walks through the correct steps before making any YAML changes

In short: Think of it as giving your AI assistant full read access to your FlutterFlow project, plus careful write access when needed.

Quick Start

1. Get Your FlutterFlow API Token

You need a FlutterFlow API token to authenticate. Here's how to get one:

• Open FlutterFlow and log in
• Click your profile picture (bottom-left corner)
• Go to Account Settings
• Scroll to the API Token section
• Click Copy to copy your token

Note: The API token requires a paid FlutterFlow subscription (Standard plan or above). Free-tier accounts do not have API access.

2. Add to Your MCP Client

Choose your AI client below and follow the setup instructions.

Claude Code (CLI)

Run this command to add the MCP server:

claude mcp add flutterflow -e FLUTTERFLOW_API_TOKEN=your_token_here -- npx -y flutterflow-mcp

Replace your_token_here with the token you copied in step 1.

This adds the server to your project's .claude/settings.json. You can also manually edit the config:

{
  "mcpServers": {
    "flutterflow": {
      "command": "npx",
      "args": ["-y", "flutterflow-mcp"],
      "env": {
        "FLUTTERFLOW_API_TOKEN": "your_token_here"
      }
    }
  }
}

Claude Desktop

Open Settings > Developer > Edit Config and add:

{
  "mcpServers": {
    "flutterflow": {
      "command": "npx",
      "args": ["-y", "flutterflow-mcp"],
      "env": {
        "FLUTTERFLOW_API_TOKEN": "your_token_here"
      }
    }
  }
}

Replace your_token_here with your token. Restart Claude Desktop after saving.

Cursor

Open Settings > MCP and add a new server with this configuration:

{
  "mcpServers": {
    "flutterflow": {
      "command": "npx",
      "args": ["-y", "flutterflow-mcp"],
      "env": {
        "FLUTTERFLOW_API_TOKEN": "your_token_here"
      }
    }
  }
}

Windsurf / Other MCP Clients

Add the following to your MCP configuration file (check your client's docs for the exact location):

{
  "mcpServers": {
    "flutterflow": {
      "command": "npx",
      "args": ["-y", "flutterflow-mcp"],
      "env": {
        "FLUTTERFLOW_API_TOKEN": "your_token_here"
      }
    }
  }
}

3. Start Building

Ask your AI assistant to list your FlutterFlow projects, inspect pages, or explore your app — it handles the rest.

Example prompts to get started:

• "List my FlutterFlow projects"
• "Show me all the pages in project X"
• "What does the HomePage do? Walk me through its widget tree"
• "Where is the PaywallCard component used?"
• "What API endpoints are configured?"
• "Show me the theme colors"

How It Works Under the Hood

This MCP is designed to make AI agents as effective as possible when working with FlutterFlow. Here's what makes it work well:

Smart Local Caching

Instead of hitting the FlutterFlow API for every question, the MCP downloads your entire project once (sync_project) and caches it locally. After that, most tools read from the cache — making them instant and free of API rate limits. If you've made changes in FlutterFlow, just re-sync to refresh the cache.

Built-in Documentation

AI models don't natively understand FlutterFlow's internal structure. This MCP ships with 21 reference documents covering every widget type, action, variable, theme setting, and editing pattern. The AI can look up exactly how a Button, Column, or Navigation action is structured — so it doesn't have to guess.

Guided Editing Workflow

Before making any change, the AI can call get_editing_guide with a plain-English description of what it wants to do (e.g., "change the button color on the login page"). The MCP returns the exact steps, relevant documentation, and rules to follow — reducing the chance of mistakes.

25 Purpose-Built Tools

Rather than one generic "read project" tool, the MCP provides 25 specialized tools — each designed for a specific task. Want to know where a component is used? There's a dedicated tool for that. Want to see all navigation actions pointing to a page? There's one for that too. This means the AI always picks the right tool for the job instead of downloading everything and searching through it.

Limitations and Cautions

Be Careful with Edits

This MCP can make changes to your FlutterFlow project, but edits should be treated with care:

• Always review before pushing — Ask your AI assistant to show you exactly what it plans to change before it pushes anything. Make sure you understand the change.
• There's no undo button for API changes — Changes are applied immediately to your project. You can roll back using FlutterFlow's version history, but it's better to prevent a bad edit than to fix one.
• Start with read-only tasks — Get comfortable asking questions about your project (page summaries, component usage, theme inspection) before asking the AI to modify anything.
• Smaller edits are safer — Editing a single widget is safer than replacing an entire page. The AI knows to make targeted changes, but it's good to be aware.

What the FlutterFlow API Can't Do

These are limitations in FlutterFlow's own API. They affect any tool that connects to FlutterFlow, not just this MCP.

• Custom code can be read but not edited — The AI can read your custom actions, custom functions, and custom widgets, but it cannot push code changes back to FlutterFlow. The API doesn't support it properly — attempting to push code corrupts the FlutterFlow editor. Instead, the AI will show you the modified code and you copy-paste it into the FlutterFlow code editor.
• Unlocked main.dart can't be updated — If you've unlocked main.dart for raw Dart editing, the AI can read it but can't push code changes. Startup/shutdown action lists can still be modified.
• Platform config files are indirect — You can't directly edit AndroidManifest.xml, Info.plist, or build.gradle. Instead, you configure hooks and settings in FlutterFlow, which generates those files for you. The AI can read and modify those hooks.
• Editing platform config files requires extra care — FlutterFlow groups all platform config files together internally. If the AI pushes a change to just one (e.g., Android Manifest), FlutterFlow may delete the others (e.g., ProGuard rules, Gradle config). The MCP handles this by always including all existing files in the same push, but it's something to be aware of.
• Disabling conditional actions works differently — In the FlutterFlow editor, you can toggle a conditional action on/off with a switch. The API handles this slightly differently, so the AI uses a workaround that achieves the same result.
• Validation isn't perfect — The validation step catches most errors, but occasionally something that passes validation can still fail when pushed. This is rare, but it's why reviewing changes before pushing is important.
• Project list may be incomplete — The API may not return all projects you have access to, especially shared or team projects. If a project is missing, copy its ID directly from the FlutterFlow editor (click the project name in the top-left corner) and paste it into your AI prompt.

General Limitations

• No live sync — The MCP works with a snapshot of your project. It doesn't watch for changes you make in the FlutterFlow editor in real time. If you've been editing in FlutterFlow, re-sync before asking the AI to make changes.
• Very large pages — Some extremely large pages may fail to load. The AI can work around this by loading individual widgets instead of the whole page.
• Cache can go stale — If you edit your project in FlutterFlow after syncing, the AI's local copy is outdated. Re-run the sync (the AI will tell you when it detects stale data).
