WHAT IT DOES

What upvote does on Reddit Skills

AI agents use upvote to create or update resources in Reddit Skills, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Reddit Skills environment.

RISK

Why upvote is rated Medium

Upvoting modifies the vote state of a Reddit post, which is a reversible write action (the vote can be removed or changed). It does not delete data, execute code, or involve financial transactions. Misuse could involve mass upvoting to manipulate Reddit's ranking/scoring system, which gives it medium severity.

From the tool's definition Upvote a Reddit post — creates a vote action on Reddit, modifying the post's score

RECOMMENDED RULE

The rule that runs upvote safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Reddit Skills, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For upvote, this is the rule to start with:

upvote Rate-limited

upvote stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "upvote": {
      "limits": [
        {
          "counter": "upvote_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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