Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| flow_generate_imageA | Generates high-fidelity images on Google Flow using Nano Banana 2, Nano Banana Pro, or Imagen 4. Supports attaching multiple reference images (e.g. character sheet + background environment) as prompt attachment chips. When auto_confirm=true, submits the prompt and downloads high-res images to output_folder. When auto_confirm=false (default), prepares the prompt and references in the UI for safety review without consuming credits. |
| flow_generate_videoA | Generates cinematic video clips on Google Flow using Veo 3.1 or Omni Flash. When auto_confirm=true, submits generation, monitors rendering progress, and downloads the MP4 file. When auto_confirm=false, prepares prompt without consuming credits. |
| flow_statusA | Checks the health and telemetry of Google Flow: Chrome CDP connection state, active user account, session expiration, and real-time remaining credit balance. |
| flow_manage_projectB | Lists existing Flow projects or creates a new project on the user canvas. |
| flow_download_latestB | Downloads the most recently rendered image or video asset from the active Flow project without re-generating. |

TDQS
Scored across 7 tools
Each tool targets a distinct concern: connection lifecycle, status, project management, image generation, video generation, and asset download. There is no meaningful overlap or ambiguity between them.
All tools follow the same flow_verb_noun pattern with snake_case, making the set predictable and easy to navigate. Even the less specific flow_manage_project fits the established convention.
Seven tools is well-scoped for a Google Flow MCP server, covering connection, status, project management, generation, and download without unnecessary duplication. Each tool earns its place.
The core workflow is covered: connect, manage projects, generate images/videos, and download results. Minor gaps exist such as no way to fetch a specific historical asset or cancel an in-progress generation, but these are not fatal to the primary use case.
