JavaScript Requires Chilkat v11.6.0+

List the Resources Offered by an MCP Server

Demonstrates Mcp.ListResources, which calls the MCP resources/list method and places the server's result (a resources array) into a JsonObject.

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

Background. The Model Context Protocol (MCP) lets a client interact with a server's tools, resources, and prompts over a standard JSON-RPC interface. This example connects to the public, no-authentication Microsoft Learn MCP server at https://learn.microsoft.com/api/mcp over Streamable HTTP.

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.

JavaScript

var success = false;

var mcp = new CkMcp();

//  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.
success = mcp.Connect("https://learn.microsoft.com/api/mcp");
if (success == false) {
    console.log(mcp.LastErrorText);
    return;
}

//  Call the MCP resources/list method.  On success, the server's result object -- containing a
//  "resources" array -- is placed in the JsonObject.  Not all servers expose resources.
var json = new CkJsonObject();
success = mcp.ListResources(json);
if (success == false) {
    console.log(mcp.LastErrorText);
    return;
}

json.EmitCompact = false;
console.log(json.Emit());
