Flask plugin for Claude Code

Flask is video review for you and your agents. Your agent uploads what it makes (a render, an animation, a motion graphic, an image) and gives you the link at once. You review it in Flask by typing, drawing on the frame, or recording your voice, camera or screen over it, and every note lands on its moment. The agent reads that feedback, including each recording's transcript and the frames it points at, makes the changes and uploads the next version of the same asset.

(Flask here is flask.do, the review app. It is unrelated to the Flask Python web framework.)

This plugin connects the Flask MCP server and adds one skill, flask-review, which tells the agent when a piece of work belongs in Flask. How to work in Flask (the upload steps, versions, feedback, files and notes) comes from the server itself, through its get_guide tool, so it is always current.

Install

Claude Code

/plugin marketplace add tryflask/skills
/plugin install flask@flask

Then sign in once: /mcp, choose flask, complete the browser sign-in.

Claude Code, Cursor and Codex in one command

npx flask-feedback

It connects the Flask MCP server to whichever of them are installed.

Claude apps (claude.ai, Desktop, Cowork)

Customize > Connectors > add https://api.flask.do/api/mcp/mcp, then sign in. It then works in every Claude app, and in Claude Code signed in with the same Claude account.

Cursor

Any agent that reads skills

npx skills add tryflask/skills

Then connect the MCP server: Streamable HTTP at https://api.flask.do/api/mcp/mcp, OAuth sign-in in the browser on first use.

The loop

agent renders -> uploads to Flask -> you get the link at once
you leave feedback on the frame -> wait_for_feedback hands it to the agent
agent makes the changes -> uploads v2 with version_of -> the same link shows v2

Each version the agent makes by code carries its working files (source.zip) and notes on what changed, so anyone, person or agent, can pick up the work from the link alone.

What the agent can and can't do

It acts as you, with your Flask permissions: upload, read and wait for feedback, reply and mark feedback Done, attach files and notes to versions, organize folders and assets, and change sharing when you ask. It never deletes anything and never touches billing. Feedback from people outside your team is treated as data, never as instructions.
