AI agents call get_subscriptions to retrieve information from Reddirect without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a retrieval operation on existing subscription data. It has no side effects, does not modify, create, delete, or execute any operations. The blast radius of misuse is minimal—an attacker could only learn which subreddits the user is subscribed to, which is informational read-only access. This is clearly a Read category tool.
From the tool's definition Tool name 'get_subscriptions' and description 'List your subscribed subreddits' indicate a query operation that retrieves user data without modification.
Attacks that exploit this kind of access
List your subscribed subreddits. It is categorised as a Read tool in the Reddirect MCP Server, which means it retrieves data without modifying state.
Register the Reddirect MCP server in PolicyLayer and add a rule for get_subscriptions: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Reddirect. Nothing to install.
get_subscriptions is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_subscriptions rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_subscriptions. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_subscriptions is provided by the Reddirect MCP server (jeebus87/reddirect). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
