WHAT IT DOES

What reddit_user_posts does on Crawlora

AI agents call reddit_user_posts to retrieve information from Crawlora without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`after`	string	—	Reddit pagination token
`limit`	integer	—	Maximum posts, defaults to 25 and clamps to 100
`username`	string	Yes	Public Reddit username, without u/

Parameters from the server's own tool schema.

RISK

Why reddit_user_posts is rated Low

Even though reddit_user_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

RECOMMENDED RULE

The rule that runs reddit_user_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_user_posts, this is the rule to start with:

reddit_user_posts Allowed

reddit_user_posts is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "reddit_user_posts": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Crawlora, apply this rule, and every reddit_user_posts call is checked against it from then on.
