Tools are an external functionality that Agents can invoke during execution.
Tools are managed from Integrations. There, you can review the Tools included in each Integration and configure project-level values such as Parameters and Credentials.
Tool definitions cannot be edited as standalone elements. You can only adjust a Tool’s configuration from the Integration that contains it.
Review Public Integrations to see which are available by default.
To incorporate your project's API, create a Private Integration. See How to create a Private Integration.
