• Every tool passes all six checks.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work.

• get_user_by_username

  Look up a Twitter/X user profile by username (handle). Returns the profile including follower and following counts. Bills one user request against the caller's balance.

• get_user_by_id

  Look up a Twitter/X user profile by numeric user ID. Bills one user request against the caller's balance.

• search_users

  Search Twitter/X user profiles by name or handle. Returns one page of matching profiles and bills against the caller's balance. Use this when you know roughly who someone is but not their exact handle.

• get_tweet

  Fetch a single Twitter/X post by its numeric ID, including engagement counts. Bills one post request against the caller's balance.

• get_tweet_thread

  Fetch one page of a Twitter/X thread — the chain of follow-up posts the author wrote under their own post ("1/", "2/", ...). Give it the ID of any post in the chain and it returns that chain in order. It does NOT return what other people…

• get_tweet_comments

  Fetch one page of replies to a Twitter/X post. Returns about 20 replies plus a next_cursor. The first item of a page can repeat the last item of the previous page, so de-duplicate by post id when paging. Each call bills against the…

• get_user_tweets

  Fetch one page of a user's own posts (excluding replies), newest first. Returns about 20 posts plus a next_cursor. If the account has a pinned post it is prepended to every page, so de-duplicate by post id when paging. Each call bills…

• get_user_tweets_and_replies

  Fetch one page of a user's posts including their replies, newest first. Returns about 20 items plus a next_cursor. If the account has a pinned post it is prepended to every page, so de-duplicate by post id when paging. Each call bills…

• get_user_mentions

  Fetch one page of posts mentioning a given user, newest first. Returns about 20 posts plus a next_cursor. The first item of a page can repeat the last item of the previous page, so de-duplicate by post id when paging. Each call bills…

• get_user_followers

  Fetch one page of a user's followers. This is one of the most expensive tools: a page is set upstream and can run to ~100 user records, every one of which is billed. Never page through a large account's followers without the user…

• get_user_following

  Fetch one page of the accounts a user follows. Expensive: a page is set upstream and can run to ~100 user records, every one of which is billed. Never page through a large account's following list without the user explicitly asking…

• check_is_following

  Check whether one Twitter/X user follows another. Far cheaper than fetching a follower list — use this whenever the question is about a specific pair of accounts. Both IDs must be numeric.

• search_tweets

  Search Twitter/X posts. Returns one page of about 20 results plus a next_cursor, and bills one search request against the caller's balance. The query supports Twitter's advanced search operators, and using them is almost always better…

• get_list_tweets

  Fetch one page of posts from a Twitter/X list, newest first. A page is large — around 100 posts — plus a next_cursor. Billing is per result, so one call here costs several times a single-user timeline call; do not page through a busy list…
