While the MCP doesn’t have a stable release tagged, I’m suspicious it hasn’t been tested much by humans at all. In going through the default setup, I noticed that it recommends a default query parameter of `order:latest-post` which looks to be hallucinated. The MCP has clearly been written with significant AI tooling. Perhaps the README needs to be updated to be clear on what has been tested and what is still in progress?

`latest-post` is a valid parameter in the `filter` route:

I think it may be a legit bug in the README… feel free to post a PR if you notice any other inaccuracies, thanks for bringing this up:
