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.

local chilkat = require("chilkat")

local mcp = chilkat.Mcp.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.
local success = mcp:connect("https://learn.microsoft.com/api/mcp")
if not success then
    print(mcp.last_error_text)
    return
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.
local json = chilkat.JsonObject.new()
success = mcp:read_resource("file:///example/resource.txt", json)
if not success then
    print(mcp.last_error_text)
    return
end

json.emit_compact = false
print(json:emit())
