WHAT IT DOES

What get_word_cloud does on PatSnap MCP Server

AI agents call get_word_cloud 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_word_cloud needs a policy

This tool retrieves and analyzes patent keyword data for trend analysis and search refinement. It performs a read-only query against PatSnap's patent database, returning aggregated statistical data (word frequency) without any side effects, state changes, or data modifications. No code execution, destructive operations, or financial transactions are involved.

From the tool's definition Tool description explicitly states it 'Obtain[s] a snapshot of frequently occurring keywords/phrases' and 'Returns up to 100 keywords.' The verb 'Obtain' and the output-focused nature indicate data retrieval with no modification, creation, or deletion of data.

POLICY

How to control get_word_cloud

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_word_cloud:

policy.json

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

get_word_cloud 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.
