The VibeFlow MCP (Model Context Protocol) server lets any MCP-compatible AI client run the canvas agent end-to-end: list and create canvases, write frames, attach skills, export to PPTX, and more. From your editor. A typical workflow: open a repo in Cursor or Claude Code, point the assistant at your codebase, and have it spin up a canvas branded with your real components, generate a launch deck, and stream the .pptx back to your machine. No browser context-switch.

What you can do via MCP

Spin up a brand-new canvas and brief itlist_canvases → (none yet) → ask user → run_canvas_agent against a new canvas (created via UI or the broader VibeFlow MCP)
Add a frame to an existing canvaslist_canvases → list_canvas_frames → create_canvas_frame

​
Getting your API key

1

Open Settings

Sign in to VibeFlow, click your avatar, go to Settings → MCP.
2

Create an API key

Click Create API Key. The key starts with vf_mcp_… and is shown once.
3

Copy URL and key

Copy the MCP URL (https://tool.vibeflow.ai/mcp unless you’ve been routed to a regional cluster) and the key.
The same key works for both canvas tools and the broader VibeFlow MCP (UI projects, design systems, deploys).

​
Transport

FieldValue
TransportStreamable HTTP
MCP URLhttps://tool.vibeflow.ai/mcp
AuthAuthorization: Bearer YOUR_API_KEY
Any MCP client that supports HTTP transport with custom headers can connect. Streaming is preserved end-to-end.

​
Connecting your client

​
Claude Code

claude mcp add --transport http \
  vibeflow https://tool.vibeflow.ai/mcp \
  --header "Authorization: Bearer YOUR_API_KEY"
Replace YOUR_API_KEY with your key.

​
Cursor

Add to ~/.cursor/mcp.json (or via the Cursor MCP settings panel): 
{
  "vibeflow": {
    "command": "npx",
    "args": [
      "-y",
      "mcp-remote",
      "https://tool.vibeflow.ai/mcp"
    ],
    "env": {
      "HTTP_AUTHORIZATION": "Bearer YOUR_API_KEY"
    }
  }
}

​
Claude Desktop

Add to your Claude Desktop config: 
{
  "mcpServers": {
    "vibeflow": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://tool.vibeflow.ai/mcp",
        "--header",
        "Authorization: Bearer YOUR_API_KEY"
      ]
    }
  }
}

​
Anything else

For any client that supports Streamable HTTP transport:
  • MCP URL: https://tool.vibeflow.ai/mcp
  • Auth header: Authorization: Bearer YOUR_API_KEY

​
A prompt to try

Once your client is connected, try this in chat to see the loop end-to-end: 
List my canvases. Pick the most recent one.

Run the canvas agent against it with this brief:

"Look at my repository's components in src/components/ui. Use them as
the design system. Generate a three-slide launch deck for our v2
release. Title slide, value-prop slide, pricing slide. Then export
the canvas as PPTX and give me the download link."
A good MCP client will chain list_canvases → run_canvas_agent → export_canvas → get_canvas_export and hand you back a working URL.

​
Pricing

MCP tool calls bill the same as in-app usage. The run_canvas_agent tool charges per-turn (token-based, 1-credit minimum). Exports and clone calls have small flat fees. See Credits for the per-tool table. The MCP doesn’t bypass credit gates. If your account is empty, the tool returns an “insufficient credits” error rather than running.

​
Regenerating your key

Settings → MCP → regenerate. The old key is invalidated immediately. Update your client config to the new key. If a key is leaked or pushed to a public repo, regenerate immediately.
