# AI Capabilities

> Available capabilities for your AI Task nodes

AI Task nodes can be equipped with a wide range of capabilities.
Each capability unlocks additional tools the agent can use during execution. We suggest starting with the default capabilities, and enabling additional ones when strictly needed.

<Tip>
  **API Tool Identifiers** — When configuring AI Task node `tools` via the API or MCP server, use the snake\_case identifiers listed below each tool. You can also call the `listAvailableTools` MCP tool or `GET /agents/available-tools` API endpoint to discover all available tools programmatically.

## Web Browsing Essentials

Core tools for basic navigation and DOM interaction.

<Warning>
  **Critical: Basic Web Interaction is Required**

  **Basic Web Interaction is enabled by default and should always remain enabled for AI Task nodes.** This capability provides essential tools for clicking, typing, selecting elements, and interacting with the DOM.

  * Disabling Basic Web Interaction will prevent AI Task nodes from performing basic browser interactions
  * You should not disable this capability unless you have a very specific reason
  * This capability is part of the default "Web Browsing Essentials" set and is required for AI Task nodes to function properly
</Warning>
