The **MCP Tools** 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.

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 **MCP Tools** component's [HTTP/SSE mode](/mcp-client#mcp-http-mode) to connect to your Langflow project's MCP server.

For more information, see [Use Langflow as an MCP client](/mcp-client) and [Use Langflow as an MCP server](/mcp-server).

:::tip Tool mode is missing
If you're upgrading an existing flow and the **MCP Tools** component loses its **Tool Mode** option, see [MCP Tools component loses Tool Mode option after upgrading flows](/troubleshoot#mcp-tools-component-loses-tool-mode-option-after-upgrading-flows).
