JavaScript Requires Chilkat v11.6.0+

Get a Prompt from an MCP Server

Demonstrates Mcp.GetPrompt, which calls the MCP prompts/get method for a named prompt, passing a JSON arguments object and receiving the prompt result.

Tip: Code to parse the returned JSON can be generated with Chilkat's online tool at https://tools.chilkat.io/jsonParse.

Background. The prompt name and its expected arguments come from the prompts array returned by ListPrompts. Pass an empty arguments object for a prompt that takes none.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

//  prompt name and its arguments come from the "prompts" array returned by ListPrompts.

//  Call the MCP prompts/get method for the named prompt.  The prompt result is placed in the
