|

These components define the behavior and capabilities of AI agents in your flows.</p>

<details class="details_lb9f alert alert--info details_b_Ee" data-collapsed="true"><summary>How do agents work?</summary><div><div class="collapsibleContent_i85q"><p>Agents extend Large Language Models (LLMs) by integrating <em>tools</em>, which are functions that provide additional context and enable autonomous task execution.
|
||
These integrations make agents more specialized and powerful than standalone LLMs.</p><p>Whereas an LLM might generate acceptable, inert responses to general queries and tasks, an agent can leverage the integrated context and tools to provide more relevant responses and even take action.
|
||
For example, you might create an agent that can access your company's documentation, repositories, and other resources to help your team with tasks that require knowledge of your specific products, customers, and code.</p><p>Agents use LLMs as a reasoning engine to process input, determine which actions to take to address the query, and then generate a response.
|
||
The response could be a typical text-based LLM response, or it could involve an action, like editing a file, running a script, or calling an external API.</p><p>In an agentic context, tools are functions that the agent can run to perform tasks or access external resources.
|
||
A function is wrapped as a <code>Tool</code> object with a common interface that the agent understands.
|
||
Agents become aware of tools through tool registration, which is when the agent is provided a list of available tools typically at agent initialization.
|
||
The <code>Tool</code> object's description tells the agent what the tool can do so that it can decide whether the tool is appropriate for a given request.</p></div></div></details>

|
||
<p>The <strong>Simple Agent</strong> template creates a basic agent flow with an <strong>Agent</strong> component that can use two other Langflow components as tools.
|
||
The LLM specified in the <strong>Agent</strong> component's settings can use its own built-in functionality as well as the functionality provided by the connected tools when generating responses.</p>

|

<p>The <strong>Agent</strong> component is the primary agent actor in your agent flows.
|
||
This component uses an LLM integration to respond to input, such as a chat message or file upload.</p>
|
||
<p>The agent can use the tools already available in the base LLM as well as additional tools that you connect to the <strong>Agent</strong> component's <strong>Tools</strong> port.
|
||
You can connect any Langflow component as a tool, including other <strong>Agent</strong> components and MCP servers through the <a href="#mcp-connection"><strong>MCP Tools</strong> component</a>.</p>
|
||
<p>For more information about using this component, see <a href="/agents">Use Langflow agents</a>.</p>
|
||
<h2 class="anchor anchorWithHideOnScrollNavbar_WYt5" id="mcp-connection">MCP Tools component<a href="#mcp-connection" class="hash-link" aria-label="Direct link to MCP Tools component" title="Direct link to MCP Tools component"></a></h2>
|
||
<p>The <strong>MCP Tools</strong> component connects to a Model Context Protocol (MCP) server and exposes the MCP server's functions as tools for Langflow agents to use to respond to input.</p>
|
||
<p>In addition to publicly available MCP servers and your own custom-built MCP servers, you can connect Langflow MCP servers, which allow your agent to use your Langflow flows as tools.
|
||
To do this, use the <strong>MCP Tools</strong> component's <a href="/mcp-client#mcp-sse-mode">SSE mode</a> to connect to your Langflow project's MCP server at the <code>/api/v1/mcp/sse</code> endpoint.</p>
|
||
<p>For more information, see <a href="/mcp-client">Use Langflow as an MCP client</a> and <a href="/mcp-server">Use Langflow as an MCP server</a>.</p>
