AI agents call reddit_search to retrieve information from Proxima without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Reddit search is a read-only operation that queries and retrieves publicly available data with no side effects. Even if the tool lacks documentation, the name unambiguously indicates search/retrieval. Low severity because misuse would only retrieve data, not modify or delete anything.
From the tool's definition Tool name 'reddit_search' indicates retrieval of publicly available Reddit content. No description provided, but naming convention and sibling tools (academic_search, analyze_document) suggest data querying without modification.
Documented attack patterns abuse exactly the kind of access reddit_search gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Proxima, and nothing reaches the server without passing your rules. This is the rule we recommend for reddit_search:
{
"version": "1",
"default": "deny",
"tools": {
"reddit_search": {}
}
}reddit_search is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

reddit_search. It is categorised as a Read tool in the Proxima MCP Server, which means it retrieves data without modifying state.
Register the Proxima MCP server in PolicyLayer and add a rule for reddit_search: 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 Proxima. Nothing to install.
reddit_search 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 reddit_search 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 reddit_search. 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.
reddit_search is provided by the Proxima MCP server (zen4-bit/proxima). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
