Tool allow list

Tools are always a strict allow list. If a tool is not listed, clients cannot call it.

UI behavior

In the Preset editor:

• Open the Tools section.
• Select tools from the connected servers list.
• Disable a tool to remove it from the preset.

Prefixed tool names

Broxy prefixes tools to avoid collisions:

• Downstream name: search
• Client name: github_search

Clients must use the prefixed name when calling tools.

Missing tools

If a preset references a tool that a server no longer exposes:

• Broxy logs a warning.
• The proxy keeps running.
• The missing tool does not appear in tools/list.

Empty tool lists

If the tools list is empty, no tools are exposed and tool calls are denied.
