Retrieves a specific Reddit comment and optionally its complete discussion thread. This tool should be used when you need to examine a particular comment
AI agents call get_comment to retrieve information from Systemprompt without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries data from Reddit (a comment and optionally its thread context) with no side effects. It does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal—an agent could retrieve comments excessively or from unintended threads, but no data is altered or destroyed. This is a straightforward data retrieval operation.
From the tool's definition Retrieves a specific Reddit comment and optionally its complete discussion thread—the verb 'retrieves' and the read-only nature of fetching existing data without modification indicates a Read operation.
Documented attack patterns abuse exactly the kind of access get_comment gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Systemprompt, and nothing reaches the server without passing your rules. This is the rule we recommend for get_comment:
{
"version": "1",
"default": "deny",
"tools": {
"get_comment": {}
}
}get_comment is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieves a specific Reddit comment and optionally its complete discussion thread. This tool should be used when you need to examine a particular comment. It is categorised as a Read tool in the Systemprompt MCP Server, which means it retrieves data without modifying state.
Register the Systemprompt MCP server in PolicyLayer and add a rule for get_comment: 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 Systemprompt. Nothing to install.
get_comment 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_comment 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_comment. 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_comment is provided by the Systemprompt MCP server (systempromptio/systemprompt-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
