# Tool catalog

> Every individual capability across all connected servers, with its own on/off switch.

The **Tool Catalog** is a flat list of every tool discovered across all of a workspace's backend servers — one row per capability, not per server.

## Namespacing

Each tool is listed with its full namespaced name (`namespace.tool`), so identically named tools from two different backends never collide.

## Per-tool toggles

Unlike the server-level enable/disable in [Backend Servers](/essentials/backend-servers), the catalog lets you turn off individual tools without disabling the whole server they came from — useful when a backend exposes more capability than you want to expose to your AI client.

A disabled tool stops appearing in `tools/list` responses from the aggregated endpoint and can't be called, even if the client requests it by name.
