AI agents call reputation_for_ip to retrieve information from SeldomMaster without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a data retrieval operation—querying IP reputation from external threat intelligence sources. It has no side effects, cannot execute code, does not modify data, and does not commit financial transactions. It aligns with the Read category pattern of 'fetch, get, search' operations that retrieve information for analysis.
From the tool's definition The tool name 'reputation_for_ip' and its description indicate a lookup/query function that retrieves reputation data for an IP address.
Documented attack patterns abuse exactly the kind of access reputation_for_ip gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SeldomMaster, and nothing reaches the server without passing your rules. This is the rule we recommend for reputation_for_ip:
{
"version": "1",
"default": "deny",
"tools": {
"reputation_for_ip": {}
}
}reputation_for_ip is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Name: reputation_for_ip. It is categorised as a Read tool in the SeldomMaster MCP Server, which means it retrieves data without modifying state.
Register the SeldomMaster MCP server in PolicyLayer and add a rule for reputation_for_ip: 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 SeldomMaster. Nothing to install.
reputation_for_ip 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 reputation_for_ip 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 reputation_for_ip. 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.
reputation_for_ip is provided by the SeldomMaster MCP server (paralax/seldommonster). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from SeldomMaster, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
