AI agents call getRedditPostsByKeywords to retrieve information from Social Media Search API — Twitter, Instagram, Reddit, TikTok (XPOZ) without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though getRedditPostsByKeywords only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Search Reddit posts by keywords with two response modes. Searches in post titles and selftext. FAST (default, omit responseType or responseType="fast"): Returns up to 300 results directly (use limit param to reduce, e.g. limit=5). Auto API fallback for fresh data. Results include guidance for full mode. PAGING (responseType="paging"): Async paginated results (100/page), returns operationId for polling via checkOperationStatus. Supports pageNumber/tableName for subsequent pages. CSV (responseType="csv"): Async single CSV download, returns operationId, poll for S3 link. CODE EXECUTION: For csv mode, download CSV and use code execution to analyze full dataset. Ideal for: sentiment analysis, subreddit trends, community discussions across thousands of posts. Returns by default: id, title, authorUsername, subredditName, createdAtDate. First searches database, then external API if data is stale or missing. QUERY SYNTAX: Plain keywords (bitcoin, climate change), quoted phrases ("deep learning"), boolean expressions (AI AND crypto, bitcoin OR ethereum, politics NOT sports), or parenthesized groups ((startup OR entrepreneur) NOT "venture capital"). AND/OR/NOT must have a term on both sides. @handles like @karpathy are supported. Field operators (from:, lang:) are stripped. Forward slashes are treated as spaces (24/7 becomes 24 7). Date filters: OMIT startDate/endDate parameters by default. ONLY pass these if user explicitly requests specific date range (YYYY-MM-DD format). IMPORTANT!!!!!: THE CURRENT YEAR IS 2026. When user requests relative dates (last week, last month), verify the current date from your system context and double-check the calculated dates - models often get the year wrong, searching one year earlier than intended. FILTERS: sort (relevance, hot, top, new, comments), time (hour, day, week, month, year, all), subreddit (limit to specific subreddit). FIELDS parameter (optional): Specify to get additional/different fields. Available: Core (id, title, selftext, url, permalink), Author (authorId, authorUsername), Subreddit (subredditName, subredditId), Engagement (score, upvotes, downvotes, upvoteRatio, commentsCount, crosspostsCount), Flags (isSelf, isVideo, over18, spoiler, locked, stickied, archived). This is a safe, read-only tool for analyzing searchable information.. It is categorised as a Read tool in the Social Media Search API — Twitter, Instagram, Reddit, TikTok (XPOZ) MCP Server, which means it retrieves data without modifying state.
