AI agents call get_mpep_section to retrieve information from Claude Patent Creator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves regulatory reference data (MPEP sections) without modifying or executing operations. It is a read-only lookup function. Severity is medium because while data retrieval itself is low-risk, patent procedure guidance could influence compliance decisions if misused. Confidence is reduced to 0.75 due to empty description; a fuller description would confirm read-only behavior.
From the tool's definition Tool name 'get_mpep_section' suggests retrieval of MPEP (Manual of Patent Examining Procedure) regulatory documentation. The description is empty, but context indicates patent creation/analysis workflows where reading procedural guidelines is necessary.

PolicyLayer is an MCP gateway — it sits between your AI agents and Claude Patent Creator, and nothing reaches the server without passing your rules. This is the rule we recommend for get_mpep_section:
{
"version": "1",
"default": "deny",
"tools": {
"get_mpep_section": {}
}
}get_mpep_section is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_mpep_section. It is categorised as a Read tool in the Claude Patent Creator MCP Server, which means it retrieves data without modifying state.
Register the Claude Patent Creator MCP server in PolicyLayer and add a rule for get_mpep_section: 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 Claude Patent Creator. Nothing to install.

Yes. Add a rate_limit block to the get_mpep_section 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_mpep_section. 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_mpep_section is provided by the Claude Patent Creator MCP server (robthepcguy/claude-patent-creator). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
