Two bugs made the Resources tab unusable in any MCP client.
read_resource returned mcp.types.TextContent, but the low-level
Server.read_resource decorator expects str, bytes or an iterable of
ReadResourceContents and reads .content / .mime_type off each item.
TextContent carries .text, so every resources/read failed at
serialisation with "'TextContent' object has no attribute 'content'".
The handler itself runs, so the error only ever reached the client and
never showed up in the server log.
No list_resource_templates handler was registered either, so the SDK
answered resources/templates/list with "Method not found". That hid the
homelable://nodes/{node_id} template read_resource already serves — it
is absent from RESOURCE_LIST because it is a template, not a concrete
URI, so nothing advertised it at all.
