<p>By default, <a href="/agents">Langflow agents</a> only include the functionality built-in to their base LLM.</p>
|
||
<p>You can attach tools to agents to provide access to additional, targeted functionality.
|
||
For example, tools can be used to create domain-specific agents, such as a customer support agent that can access a company's knowledge base, a financial agent that can retrieve stock prices, or a math tutor agent that can use advanced math functions to solve complex equations.</p>
|
||
<h2 class="anchor anchorWithHideOnScrollNavbar_WYt5" id="attach-tools">Attach tools<a href="#attach-tools" class="hash-link" aria-label="Direct link to Attach tools" title="Direct link to Attach tools"></a></h2>
|
||
<p>To attach a tool to an agent, you connect any component's <strong>Tool</strong> output to the <strong>Agent</strong> component's <strong>Tools</strong> input.</p>
|
||
<p>Some components emit <strong>Tool</strong> output by default.
|
||
For all other components, you must enable <strong>Tool Mode</strong> in the <a href="/concepts-components#component-menus">component's header menu</a>.
|
||
Then, you can connect the tool to the agent.</p>
|
||
<p>You can connect multiple tools to one agent, and each tool can have multiple actions (functions) that the agent can call.</p>
|
||
<p>When you run your flow, the agent decides when to call on certain tools, if it determines that a tool can help it respond to the user's prompt.</p>

||
<h3 class="anchor anchorWithHideOnScrollNavbar_WYt5" id="edit-a-tools-actions">Edit a tool's actions<a href="#edit-a-tools-actions" class="hash-link" aria-label="Direct link to Edit a tool's actions" title="Direct link to Edit a tool's actions"></a></h3>
|
||
<p>When you attach components to an agent as tools, each tool can have multiple actions (functions) that the agent can call.
|
||
Available actions are listed in each tool component's <strong>Actions</strong> list.</p>
|
||
<p>You can change each action's labels, descriptions, and availability to help the agent understand how to use the tool and prevent it from using irrelevant or undesired actions.</p>

<p>To view and edit a tool's actions, click <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="lucide lucide-settings2" aria-hidden="true"><path d="M20 7h-9"></path><path d="M14 17H5"></path><circle cx="17" cy="17" r="3"></circle><circle cx="7" cy="7" r="3"></circle></svg> <strong>Edit Tool Actions</strong> on the tool component.</p>
|
||
<p>The following information is provided for each action:</p>
|
||
<ul>
|
||
<li>
|
||
<p><strong>Enabled</strong>: A checkbox that determines whether the action is available to the agent.
|
||
If selected, the action is enabled.
|
||
If not selected, the action is disabled.</p>
|
||
</li>
|
||
<li>
|
||
<p><strong>Name</strong>: A human-readable string name for the action, such as <code>Fetch Content</code>. This cannot be changed.</p>
|
||
</li>
|
||
<li>
|
||
<p><strong>Description</strong>: A human-readable description of the action's purpose, such as <code>Fetch content from web pages recursively</code>.
|
||
To edit this value, double-click the action's row to open the edit pane.
|
||
Changes are saved automatically when you click out of the field or close the dialog.</p>
|
||
</li>
|
||
<li>
|
||
<p><strong>Slug</strong>: An encoded name for the action, usually the same as the name but in snake case, such as <code>fetch_content</code>.
|
||
To edit this value, double-click the action's row to open the edit pane.
|
||
Changes are saved automatically when you click out of the field or close the dialog.</p>
|
||
</li>
|
||
</ul>
|
||
<p>Some actions allow you to provide fixed values for their inputs.
|
||
Typically, you want to leave these blank so the agent can provide its own values.
|
||
However, you might use a fixed value if you're trying to debug an agent's behavior or your use case requires a fixed input for an action.</p>

|
||
<p>To create multi-agent flows, you can set another <strong>Agent</strong> component to <strong>Tool Mode</strong>, and then attach that agent as a tool for your primary <strong>Agent</strong> component.</p>
|
||
<p>To try this for yourself, add an additional agent to the <strong>Simple Agent</strong> template:</p>
|
||
<ol>
|
||
<li>
|
||
<p>Create a flow based on the <strong>Simple Agent</strong> template.</p>
|
||
</li>
|
||
<li>
|
||
<p>Add a second <strong>Agent</strong> component to the flow.</p>
|
||
</li>
|
||
<li>
|
||
<p>Add your <strong>OpenAI API Key</strong> to both <strong>Agent</strong> components.</p>
|
||
</li>
|
||
<li>
|
||
<p>In the second <strong>Agent</strong> component, change the model to <code>gpt-4.1</code>, and then enable <strong>Tool Mode</strong>.</p>
|
||
</li>
|
||
<li>
|
||
<p>Click <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="lucide lucide-settings2" aria-hidden="true"><path d="M20 7h-9"></path><path d="M14 17H5"></path><circle cx="17" cy="17" r="3"></circle><circle cx="7" cy="7" r="3"></circle></svg> <strong>Edit Tool Actions</strong> to <a href="#edit-a-tools-actions">edit the tool's actions</a>.</p>
|
||
<p>For this example, change the action's slug to <code>Agent-gpt-41</code>, and set the description to <code>Use the gpt-4.1 model for complex problem solving</code>.
|
||
This lets the primary agent know that this tool uses the <code>gpt-4.1</code> model, which could be helpful for tasks requiring a larger context window, such as large scrape and search tasks.</p>
|
||
<p>As another example, you could attach several specialized models to a primary agent, such as agents that are trained on certain tasks or domains, and then the primary agent would call each specialized agent as needed to respond to queries.</p>
|
||
<p>You can also enable and disable tools if you want to limit the available toolset.</p>
|
||
</li>
|
||
<li>
|
||
<p>Connect the new agent's <strong>Toolset</strong> port to the existing agent's <strong>Tools</strong> port.</p>

<p>If the component you want to use as a tool doesn't have a <strong>Tool Mode</strong> button, add <code>tool_mode=True</code> to one of the component's inputs, and connect the new <strong>Toolset</strong> output to the agent's <strong>Tools</strong> input.</p>
|
||
<p>Langflow supports <strong>Tool Mode</strong> for the following data types:</p>
|
||
<ul>
|
||
<li><code>DataInput</code></li>
|
||
<li><code>DataFrameInput</code></li>
|
||
<li><code>PromptInput</code></li>
|
||
<li><code>MessageTextInput</code></li>
|
||
<li><code>MultilineInput</code></li>
|
||
<li><code>DropdownInput</code></li>
|
||
</ul>
|
||
<p>For example, the example code in <a href="#components-as-tools">Use custom components as tools</a> included <code>tool_mode=True</code> to the <code>MessageTextInput</code> input so the custom component could be used as a tool:</p>

|

<p>An agent can use your other flows as tools with the <a href="/components-logic#run-flow"><strong>Run Flow</strong> component</a>.</p>
|
||
<ol>
|
||
<li>Add a <strong>Run Flow</strong> component to your flow.</li>
|
||
<li>Select the flow you want the agent to use as a tool.</li>
|
||
<li>Enable <strong>Tool Mode</strong>.
|
||
The selected flow becomes an <a href="#edit-a-tools-actions">action</a> in the <strong>Run Flow</strong> component.</li>
|
||
<li>Connect the <strong>Run Flow</strong> component's <strong>Tool</strong> output to the <strong>Agent</strong> component's <strong>Tools</strong> input.</li>
|
||
<li>Open the <strong>Playground</strong>, and then ask the agent, <code>What tools are you using to answer my questions?</code>
|
||
Your flow should be visible in the response as an available tool.</li>
|
||
<li>Ask the agent a question that specifically uses the connected flow as a tool.
|
||
The connected flow returns an answer based on your question.</li>
