{"jsonrpc":"2.0","id":1,"method":"tools/list"}reddit_history_posts — Historical Reddit POSTS from one subreddit, back to ~2005 — via the Arctic Shift archive, not the live Reddit API (which the `reddit` pack uses and which only reaches ~1,000 recent results with no reliable date filter). PREFER for "Reddit posts about X in/before <year>", "what did r/<sub> post about Y historically", or any request the live reddit pack cannot date-filter. Filter by date range (after/before, ISO dates like "2019-01-01") and/or keyword (query, matched against title+body). Returns id, title, author, created_utc (ISO), score, num_comments, permalink. A subreddit Arctic Shift has never indexed is reported as a loud error, never a silent empty list.reddit_history_comments — Historical Reddit COMMENTS via the Arctic Shift archive — scope to a subreddit, a specific post (link_id), or both; requires at least one. Optionally filter by keyword (query, matched against comment body) and date range (after/before, ISO dates). Returns id, author, created_utc (ISO), score, body, link_id, permalink. No per-author aggregation is provided by this pack — results are the raw comments Arctic Shift's filters match, nothing rolled up into a user profile.subreddit_activity — Reddit subreddit identity and activity over time, via the Arctic Shift archive: subscriber count, subreddit creation date, all-time post/comment totals, earliest indexed post/comment, and monthly post/comment counts within a date window (default: the last 12 months). A subreddit Arctic Shift has never indexed is reported as a loud not-found error, never a silent empty result.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
