MCP Node

Call tools on your MCP server from within a conversation flow.

MCP node is used to call tools on your MCP server. It’s not intended for having a conversation with the user, but the agent can still talk while in this node if needed.

Add MCP Server

1. Add MCP server

   To create an MCP node, first add an MCP server connection.

2. Set request headers (optional)

   Define custom headers to include with requests sent to your MCP server.

3. Set query parameters (optional)

   Define query parameters to append to your MCP server endpoint URL.

4. Add MCP Tool

   Select the MCP tool to use.

5. Set response variables (optional)

   Extract values from the MCP tool response and save them as dynamic variables for use later in the conversation.

   For example, extract a user’s name from the response and reference it later using {{user_name}}.

   {
     "properties": {
       "user": {
         "name": "John Doe",
         "age": 26
       }
     }
   }
