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: Boolean;
mcp: HCkMcp;
json: HCkJsonObject;

begin
success := False;

mcp := CkMcp_Create();

//  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 := CkMcp_Connect(mcp,'https://learn.microsoft.com/api/mcp');
if (success = False) then
  begin
    Memo1.Lines.Add(CkMcp__lastErrorText(mcp));
    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 := CkJsonObject_Create();
success := CkMcp_ReadResource(mcp,'file:///example/resource.txt',json);
if (success = False) then
  begin
    Memo1.Lines.Add(CkMcp__lastErrorText(mcp));
    Exit;
  end;

CkJsonObject_putEmitCompact(json,False);
Memo1.Lines.Add(CkJsonObject__emit(json));
//  JSON parsing code for this result can be generated at Chilkat's online tool:
//  https://tools.chilkat.io/jsonParse

CkMcp_Dispose(mcp);
CkJsonObject_Dispose(json);
