Read a Resource from an MCP Server

See more MCP Client Examples

Demonstrates Mcp.ReadResource, which calls the MCP resources/read method for a resource identified by URI and places the contents into a JsonObject.

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;
  }

  // Read a specific resource by its URI.  A resource URI is obtained from the "resources" array
  // returned by ListResources.  The resource contents are placed in the JsonObject.
  const json = new JsonObject();
  try {
    await mcp.readResourceAsync('file:///example/resource.txt', json);
  } catch {
    console.log(mcp.lastErrorText);
    return;
  }

  json.emitCompact = false;
  console.log(json.emit());
