Get a Prompt from an MCP Server

See more MCP Client Examples

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.

let mcp = chilkat::Mcp::new();

// Connect to a public MCP (Model Context Protocol) server over its Streamable HTTP endpoint.  The
// Microsoft Learn MCP server is public and requires no authentication.
if mcp.connect("https://learn.microsoft.com/api/mcp").is_err() {
    println!("{}", mcp.last_error_text());
    return;
}

// Build the prompt's arguments (pass an empty object for a prompt that takes no arguments).  The
// prompt name and its arguments come from the "prompts" array returned by ListPrompts.
let args = chilkat::JsonObject::new();
let _ = args.update_string("topic", "azure-storage");

// Call the MCP prompts/get method for the named prompt.  The prompt result is placed in the
// JsonObject.
let json = chilkat::JsonObject::new();
if mcp.get_prompt("example-prompt", &args, &json).is_err() {
    println!("{}", mcp.last_error_text());
    return;
}

json.set_emit_compact(false);
println!("{}", json.emit().unwrap_or_default());
