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.

    success := false

    mcp := chilkat.NewMcp()

    //  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 {
        fmt.Println(mcp.LastErrorText())
        mcp.DisposeMcp()
        return
    }

    //  Perform an MCP request.
    toolsResult := chilkat.NewJsonObject()
    success = mcp.ListTools(toolsResult)
    if success == false {
        fmt.Println(mcp.LastErrorText())
        mcp.DisposeMcp()
        toolsResult.DisposeJsonObject()
        return
    }

    //  Get the complete JSON-RPC response envelope (the jsonrpc, id, and result members) from the most
    //  recent request.
    json := chilkat.NewJsonObject()
    mcp.GetLastJsonData(json)

    json.SetEmitCompact(false)
    fmt.Println(*json.Emit())
    //  JSON parsing code for this result can be generated at Chilkat's online tool:
    //  https://tools.chilkat.io/jsonParse

    mcp.DisposeMcp()
    toolsResult.DisposeJsonObject()
    json.DisposeJsonObject()
