Your Question

Hi there,
Quick question: If I want to expose a Markdown file as a resource.

Is this the correct approach, or should I implement a ResourceHandler?

     [McpServerResource(UriTemplate = "prompt://documentation", Name = "Prompt Documentation", MimeType = "text/markdown")]
      public static string PromptDocumentation() => System.IO.File.ReadAllText(System.IO.Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, "prompt.md"));
  }

I saw FastMcp has FileResource

from mcp.server.fastmcp.resources import FileResource, TextResource, HttpResource, DirectoryResource

laptop_specs = FileResource(
    uri="file:///specs.txt",
    path=Path("E:\\Personal\\Python\\MCP-Server\\specs.txt"),  # Absolute path to the file
    name="Laptop Specs",
    description="Specifications of the laptop"
)

Is this a possible implementation? Could we also have the C# SDK?

That's fine. Every request for that resource will call PromptDocumentation() and read and return the file.

Could we also have the C# SDK?

Have what, specifically? You can already write it as you did, or if you want to manually call McpServerResource.Create, you can do that as well. What is it "FileResource" is providing that you're asking for?
