JavaScript Requires Chilkat v11.6.0+
JavaScript
Close an MCP Session
See more MCP Client Examples
Demonstrates Mcp.Close, which explicitly terminates the MCP session by sending an HTTP DELETE with the Mcp-Session-Id header and releasing the connection.
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.

// 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);

// Explicitly terminate the MCP session. This sends an HTTP DELETE with the Mcp-Session-Id header
