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.

var
success: Integer;
mcp: TChilkatMcp;
json: TChilkatJsonObject;

begin
success := 0;

mcp := TChilkatMcp.Create(Self);

//  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 = 0) then
  begin
    Memo1.Lines.Add(mcp.LastErrorText);
    Exit;
  end;

//  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.
json := TChilkatJsonObject.Create(Self);
success := mcp.ReadResource('file:///example/resource.txt',json.ControlInterface);
if (success = 0) then
  begin
    Memo1.Lines.Add(mcp.LastErrorText);
    Exit;
  end;

json.EmitCompact := 0;
Memo1.Lines.Add(json.Emit());
