MCP stands for Model Context Protocol. It is an open standard that lets AI agents talk to external tools in a structured way. An MCP Node in GoHighLevel is a workflow step that wraps an MCP tool call. When the workflow reaches that step, GoHighLevel sends a request to the external MCP server, gets a response, and uses the result to continue the workflow.
For example, you could build an MCP Node that calls a real estate listing API to look up property details when a lead submits a form. The node returns the listing data, and the next workflow step uses it to send a personalized reply with the property information.
MCP Nodes make GoHighLevel automations much smarter. Instead of only reading and writing GoHighLevel CRM data, your workflows can pull live data from any system that exposes an MCP server: inventory systems, booking platforms, pricing tools, or your own custom backend.
How MCP Node works
You add an MCP Node to a workflow and configure it with the MCP server URL, the tool name, and the input parameters. GoHighLevel sends a JSON-RPC request to the MCP server when the workflow runs. The server processes the request and returns a result. The workflow stores that result and you can use it in later steps.
MCP Nodes work best when paired with Agent Studio agents, because agents can decide which tool to call based on the conversation context. But MCP Nodes also work in standard workflow automations as a plain HTTP call with MCP formatting.
