3.A.2 Call MCP Tool
This action allows you to send a request to an MCP server tool that has been previously configured in Settings > AI Tools > MCP Client.
This action provides a deterministic response from an MCP tool, unlike what could be achieved through an AI agent.
Users can therefore implement their own “agent” within a process by combining interactions between LLM calls and MCP tool calls.
Once an MCP client and the desired tool have been selected, the expected Input Parameters and Output Fields defined by the tool are loaded automatically and can be modified according to the tool response.
Figure 1 - Example of a Web Search Tool Call
Normally, tools return results in a format suitable for interpretation by an LLM model. Therefore, the response should be reviewed and processed before being included in a workflow.
Example of a response from the web_search_exa tool to the question: “What is the certified email (PEC) address of VTENEXT?”
