The mcp__trello__get_card tool signature:
- cardId (required): string - ID of the card to fetch
- includeMarkdown (optional, default=false): boolean - return markdown format

Call needed:
mcp__trello__get_card(cardId="6a1d64277ddbf0d220035bbb", includeMarkdown=true)

Since I loaded the tool via ToolSearch, I should be able to invoke it.
Let me try using it as if it were available as a Python function via the MCP.
