Copy button overlaps long text in Inspector output #769
Description
Describe the bug
In the MCP Inspector Tools panel, when a tool returns a long text output, the "copy" button overlaps the text content instead of staying aligned to the side. This makes part of the result unreadable.
To Reproduce
Steps to reproduce the behaviour:
- Start MCP Inspector
- Run a tool that returns a long string output (e.g. generate a long paragraph with a greet or custom tool)
- Observe that the copy button floats on top of the text, overlapping it
Expected behavior
The copy button should remain separated from the text (aligned to the right margin or above). It should not cover or obscure any part of the tool’s output, regardless of text length.
Logs
Not applicable — this is a UI layout issue.
Additional context
MCP Inspector version: v0.16.5
OS/Browser: macOS (Safari/Chrome)
Screenshot attached
Possible fix: : add padding-right to the text container so it leaves space for the button.

Closing: v1 is deprecated.
Thank you for reporting this, and apologies for the long wait for a response.
v1 will receive security fixes only — this issue describes a functionality, compatibility, or usability problem rather than a vulnerability, so it is being closed against v1. This is not a judgment on whether the problem is real — it's a consequence of the v1 line being frozen. This is happening as part of #1872.
If this still happens in v2, we'd genuinely like to know. v2 is a complete rewrite — three clients over a shared core — so many v1 behaviours no longer exist in the same form. Please open a fresh issue against v2 with steps to reproduce, and we'll look at it. Note that we accept external contributions as issues rather than pull requests; maintainers handle design and implementation through a prompt-driven workflow. See
CONTRIBUTING.md.Thanks for taking the time to report it.
