Sorry about that @marekdano Everything should work now with no issues!

Thanks for the contribution @omorros — the original bug report (#3082) was a real issue and your diagnosis of the |tojson double-quote collision was correct.

However, this fix has been superseded by the introduction of the tojson_attr custom Jinja2 filter in #3350 (merged 2026-03-01), which properly addresses the root cause. Specifically:

• tojson_attr (mcpgateway/main.py:3000) JSON-encodes the value, Unicode-escapes dangerous characters (&, <, >, '), and returns a plain str so Jinja2 autoescape HTML-encodes the remaining " — keeping double-quoted HTML attributes intact.
• Both gateways_partial.html:42 and admin.html:5297 already use |tojson_attr for the fetchToolsForGateway call on current main.
• Every other Jinja-templated event handler across all partials consistently uses |tojson_attr.

Switching to raw '{{ gateway.name }}' would weaken defense-in-depth: while input validation currently blocks quotes in gateway names, tojson_attr ensures template-level safety independent of validation rules. Merging this would also introduce an inconsistency against the established pattern.

Closing as superseded by #3350. Thanks again for reporting the issue and putting together the fix — it helped drive the proper solution.
