MCP Usage Limits

Flowstep usage limits apply at the organization level and are shared between the web app and the MCP server. A generation kicked off in Cursor counts against the same quota as one started from app.flowstep.ai.

How limits work

Limits are per-feature (the primary feature is messages). Each plan defines:

A daily limit — resets at 00:00 UTC every day
A monthly limit — resets on the date of the account sign up or paid subscription start each month

Hitting either limit blocks further generations until it resets.

Checking your quota

Call get-plan-details to see your current limits, usage, and remaining quota:

// Response (excerpt)
{
  "limits": {
    "messages": {
      "daily": { "max": 50, "warn": 40 },
      "monthly": { "max": 500, "warn": 400 },
      "unlimited": false
    }
  },
  "usage": {
    "messages": { "daily": 12, "monthly": 87 }
  },
  "remaining": {
    "messages": { "daily": 38, "monthly": 413 }
  }
}

Actual limit values depend on your plan. Run the tool to see your specific numbers. See Pricing for per-plan details.

Per-request limits (all plans)

These limits are enforced at the request level regardless of plan:

Limit	Value
Max attachments per `create-new-design` / `edit-design` call	5
Max attachment size	3 MB
Supported attachment types	`image/jpeg`, `image/png`, `image/webp`, `application/pdf` (base64), plus text/code files — `.html`, `.htm`, `.js`, `.ts`, `.jsx`, `.tsx` — as plain UTF-8
Generation timeout (`create-new-design`, `edit-design`, `regenerate-design`, `expand-design`)	180 seconds

Failed generations don’t count

If a generation request fails — due to a timeout, a server error, or an invalid input — it does not consume a message.
