[Bug] MCP tool input parameters misaligned with long tool names causing poor readability

Resolved 💬 3 comments Opened Mar 14, 2026 by Crazytieguy Closed Mar 17, 2026

Bug Description
When Claude calls an MCP tool, the input parameters are displayed indented to align with the end of the tool label. The label includes the full namespaced name, description, and an (MCP) suffix — e.g., plugin:playwright:playwright - Run Playwright code (MCP)(. When the label is long, the content is pushed so far right that the remaining column width is tiny and hard to read.
