Defining MCP Server Resources

You're expanding your MCP server for currency conversion to give it access to the list of currencies supported by the API you're using. The European Central Bank publishes a list of currency codes in a file called currencies.txt that is available in your server directory. This could be used by the client to ensure that the LLM is passing the correct argument values to the tool functions.

Your task is to define an MCP resource called get_currencies() that reads the contents of currencies.txt.

Instructions

100 XP
  • Use the correct decorator and the "file://currencies.txt" URI to convert the get_currencies() function into a resource.
  • Complete the get_currencies() function to open and read the contents of the currencies.txt file.
  • Print the result of calling get_currencies() to verify the resource works correctly.
