time | string | — | Time window for top sort: hour, day, week, month, year, or all |

limit | integer | — | Maximum posts, defaults to 25 and clamps to 100 |
subreddit | string | Yes | Subreddit name, without r/ |

Why reddit_subreddit_posts is rated Low
Even though reddit_subreddit_posts only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs reddit_subreddit_posts safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Crawlora, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For reddit_subreddit_posts, this is the rule to start with:
reddit_subreddit_posts is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Crawlora, apply this rule, and every reddit_subreddit_posts call is checked against it from then on.
