WHAT IT DOES

What get_top_assignees does on PatSnap MCP Server

AI agents call get_top_assignees to retrieve information from PatSnap MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why get_top_assignees needs a policy

This tool retrieves and analyzes existing patent data to identify leading assignees by portfolio size. It is a query operation with no side effects—it cannot modify data, execute external operations, or create financial obligations. The read operation is limited in blast radius since it accesses only pre-existing, aggregated patent metrics. Low severity reflects the purely informational nature of the output.

From the tool's definition Tool returns aggregated patent portfolio data for top companies; keywords like 'shows', 'identify', and 'returns' indicate data retrieval. No modification, deletion, execution, or financial impact is possible.

POLICY

How to control get_top_assignees

PolicyLayer is an MCP gateway — it sits between your AI agents and PatSnap MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_top_assignees:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_top_assignees": {}
  }
}

get_top_assignees is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register PatSnap MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
