```json
{
  "jsonrpc": "2.0",

## Why update_card_visualization is rated Medium

The tool modifies card visualization properties but does not delete the underlying card or data. Changes to visualization settings are reversible—they can be updated again or reverted to previous states. This places it squarely in the Write category.

From the tool's own definition: "Tool updates visualization settings for a card in Metabase. The description indicates modification of existing card configuration ('Update visualization settings'), which is a write operation that creates or modifies data reversibly."

## Use case

AI agents use update_card_visualization to create or update resources in Metabase Analytics Integration Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Metabase Analytics Integration Server environment.
