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.

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
    }

    //  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.
    let json = CkoJsonObject()!
    success = mcp.readResource(uri: "file:///example/resource.txt", json: json)
    if success == false {
        print("\(mcp.lastErrorText!)")
        return
    }

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