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.

require 'chilkat'

success = false

mcp = Chilkat::CkMcp.new()

#  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)
    print mcp.lastErrorText() + "\n";
    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 = Chilkat::CkJsonObject.new()
success = mcp.ReadResource("file:///example/resource.txt",json)
if (success == false)
    print mcp.lastErrorText() + "\n";
    exit
end

json.put_EmitCompact(false)
print json.emit() + "\n";
