Batch-fetch full tweet objects by their numeric tweet IDs. Pass a comma-separated string of up to 100 IDs. Use this when you already have specific tweet IDs (e.g., from a search result, a URL, or a webhook event) and need the full tweet data — author, text, engagement counts, media, etc.

Description, as the server wrote it:

```untrusted-server-text
⚠[U+FE0F] ONLY for 'latest / recent / what's new' queries about a user. DO NOT use for date-range queries (e.g. 'tweets from January 2026', 'tweets last week', 'tweets between X and Y', 'tweets in 2025'). For specific dates / older tweets, use **search_tweets** with query like 'from:elonmusk since:2026-01-01 until:2026-02-01'.

Fetch the MOST RECENT tweets posted by a Twitter/X user, sorted by created_at descending (newest first). Provide EITHER userName (screen name, no @) OR userId (numeric). Use userId when known — handles can change. Set includeReplies=true to include the user's reply tweets in addition to top-level tweets. Paginates via cursor (~20 per page).
```

### `get_user_mentions`

Description, as the server wrote it:

```untrusted-server-text
Fetch tweets that mention a specific Twitter/X user (i.e. tweets containing @userName). Useful for brand monitoring, sentiment tracking on a public figure, or finding conversations involving an account. Supports time-bound queries via sinceTime/untilTime (Unix seconds). Paginates via cursor.
```

### `search_tweets`

- The name "search_tweets" says "search": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The name "search_tweets" says "search" and "tweet": it reads posts, which other people can write. The description's first sentence says "tweet": it reads posts, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
🎯 PRIMARY CHOICE for date-range / historical / keyword-based tweet queries. Use this (NOT get_user_last_tweets) whenever user asks about a SPECIFIC TIME RANGE or historical tweets:
  • 'tweets from January 2026' → query='from:elonmusk since:2026-01-01 until:2026-02-01'
  • 'tweets between X and Y' → 'from:USER since:X until:Y'
  • 'tweets last week / last month' → translate to since:/until: dates
  • 'tweets containing keyword X by user Y' → 'from:Y X'
  • 'older tweets' / 'archive' / 'in 2025' → use date range, not pagination

Date format: YYYY-MM-DD (UTC midnight). 'until:' is exclusive (until:2026-02-01 = up to Jan 31).

General: Search Twitter/X for tweets matching a query. Supports the full Twitter advanced search syntax (from:, to:, since:, until:, lang:, filter:, has:, -, OR, etc). Returns ~20 tweets per page in reverse chronological order ('Latest') or by engagement ('Top'). Use this for keyword research, monitoring mentions of a brand/topic, finding tweets in a date range, or any open-ended tweet discovery.
```
