# Tools

> Give your agents external capabilities — from connected apps to custom integrations.

Tools give your agents the ability to take action beyond generating text — sending messages, fetching data, updating records in other services. The Tools page is where you set them up.

## The Tools page

The Tools page has two parts:

<CardGroup cols={2}>
  <Card title="My Tools" icon="toolbox">
    The tools you've already connected or configured. These are ready to attach to agents.
  </Card>

  <Card title="Available Tools to Add" icon="grid">
    A catalog of ready-made integrations for popular apps and services, grouped by category. When available, you can connect any of these in a few clicks.
  </Card>
</CardGroup>

## Connecting an integration

When the integrations catalog is enabled for your organization, find the app you want under **Available Tools to Add** and click **Connect**. You'll be guided through authorizing your account for that service — see [Tool connections](/agents-models-tools/tool-connections) for the full flow.

Once connected, the integration appears under **My Tools** and can be attached to any agent.

## Adding a custom tool

To connect a service that isn't in the catalog, click **Add New Tool** in the page header. You can create two kinds of custom tool:

* **API tool** — calls an HTTP endpoint. You provide a name and description, the URL and HTTP method, the authentication type (none, bearer token, API key, or basic auth), any headers and path or query parameters, and — for methods that send a body — a JSON request body.
* **MCP tool** — connects to a Model Context Protocol server. You provide a name and description, the transport type, the server URL, and any headers.

## Managing tools

From each tool card in **My Tools** you can:

* **Edit** — update its configuration.
* **Test** — try the tool with sample input to confirm it works.
* **Disconnect** — for connected integrations, remove the link to your account.
* **Delete** — remove the tool entirely.

Built-in **default tools** show **Fork & Edit** instead of Edit — creating your own editable copy of the tool rather than changing the original.

## Using tools in workflows

Tools don't act on their own — you attach them to an **Agent**. The agent decides when to call a tool based on its instructions and the task. See [Configuring agents](/building-workflows/configuring-agents#tools).
