Get the Last JSON-RPC Response from an MCP Server

See more MCP Client Examples

Demonstrates Mcp.GetLastJsonData, which returns the complete JSON-RPC response envelope (the jsonrpc, id, and result members) from the most recent request into a JsonObject.

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

func chilkatTest() {
    var success: Bool = false

    let mcp = CkoMcp()!

    //  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(url: "https://learn.microsoft.com/api/mcp")
    if success == false {
        print("\(mcp.lastErrorText!)")
        return
    }

    //  Perform an MCP request.
    let toolsResult = CkoJsonObject()!
    success = mcp.listTools(json: toolsResult)
    if success == false {
        print("\(mcp.lastErrorText!)")
        return
    }

    //  Get the complete JSON-RPC response envelope (the jsonrpc, id, and result members) from the most
    //  recent request.
    let json = CkoJsonObject()!
    mcp.getLastJsonData(json: json)

    json.emitCompact = false
    print("\(json.emit()!)")
    //  JSON parsing code for this result can be generated at Chilkat's online tool:
    //  https://tools.chilkat.io/jsonParse
