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.

import { JsonObject, Mcp } from '@chilkat/react-native'

async function chilkatExample() {
  const mcp = new Mcp();

  // 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.
  try {
    await mcp.connectAsync('https://learn.microsoft.com/api/mcp');
  } catch {
    console.log(mcp.lastErrorText);
    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.
  const args = new JsonObject();
  args.updateString('topic', 'azure-storage');

  // Call the MCP prompts/get method for the named prompt.  The prompt result is placed in the
  // JsonObject.
  const json = new JsonObject();
  try {
    await mcp.getPromptAsync('example-prompt', args, json);
  } catch {
    console.log(mcp.lastErrorText);
    return;
  }

  json.emitCompact = false;
  console.log(json.emit());
  // JSON parsing code for this result can be generated at Chilkat's online tool:
