# Tool Gating

> Pick which tools an agent can call.

Each agent can be limited to a chosen set of tools. Leave the list empty to give the agent every tool, or pick a subset to keep it focused. Tools are the actions the agent can take. Reading a record, searching records, sending an email, and so on.

## Why gate tools

* A read-only research agent shouldn't be able to write to records. Limit it to read, search, and web research tools.
* A schema-design agent that builds new objects needs the blueprint tools but not email.
* A property auto-fill agent's actions are already determined by the auto-fill itself, so extra tool gating is generally unnecessary for it.

## The web-access toggle

Turning off web access removes the agent's web search and browsing tools regardless of which other tools it's allowed to use. Use this for agents that must stay air-gapped from the public internet.
