Tools - Custral Docs

Tools are the actions available to chat agents. When the AI decides to take an action, it calls a tool. The tool runs, and its result is fed back to the AI so it can continue the conversation. This is what lets an agent do more than talk: it can look up a record, draft an email, or search the web on your behalf.

Looking for what you can actually ask? See the capability library, a plain-language catalog with example prompts.

Web-access tools

Some tools reach the public internet, web search and browsing. You can keep an agent fully air-gapped from the web by turning off its web access; doing so removes these tools regardless of which other tools the agent is allowed to use.

Per-agent gating

Each chat 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. See Tool gating for how to set this up.
