Use your MCP request to interact with an MCP server

You interact with a Model Context Protocol (MCP) server with MCP requests. As you interact with the server, it returns a response.

Interact with the MCP server

To interact with the MCP server, do the following:

1. Choose an existing MCP request or create a new one.

2. In the Capabilities section, select Load Methods. If prompted (STDIO), review the request to grant access to your computer and grant or deny it. Postman connects to the server and displays the server's methods.

3. List the server's methods:

   • To list the tools methods, select the Tools tab.
   • To list the prompts methods, select the Prompts tab.
   • To list the resources methods, select the Resources tab.

   You can also Search for a method.

4. Select a method and define its arguments. Postman creates your JSON Message for you.

5. Select Run.

Postman returns your JSON response. You can also Preview the response. In addition, you can Copy and Search the response, and Unwrap Lines or Wrap Lines.

Postman also lists Server Events. You can Search events, filter by event type, and Clear Messages. To see the event's details, select it. Each event includes an event type and timestamp.

You can also see whether you're Connected or Disconnected. To disconnect from the server, select Disconnect next to Run. To reconnect, select Connect. If there are any errors, Postman displays a counter next to the connection status. Select the count to list the errors.
