Provides a breakdown of the simple legal status (e.g., Active, Inactive, Pending) for patents in the technology field. Understand the proportion of patents currently in effect. Note: Search must contain either keywords or IPC. If both are provided, IPC is prioritized.
AI agents call get_simple_legal_status 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.
This tool retrieves and queries patent legal status information from PatSnap's API to support trend analysis and reporting. It is a read-only operation that returns status proportions (Active, Inactive, Pending) without creating, modifying, deleting, or executing any operations. The requirement to include keywords or IPC in the search confirms this is a data retrieval/query function.
From the tool's definition Tool provides a breakdown and understanding of patent legal status data; the description uses 'Provides' and 'Understand' indicating data retrieval with no modification, deletion, or execution of external operations.
Documented attack patterns abuse exactly the kind of access get_simple_legal_status gives an agent:
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_simple_legal_status:
{
"version": "1",
"default": "deny",
"tools": {
"get_simple_legal_status": {}
}
}get_simple_legal_status is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Note: Search must contain either keywords or IPC. If both are provided, IPC is prioritized. It is categorised as a Read tool in the PatSnap MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PatSnap MCP Server MCP server in PolicyLayer and add a rule for get_simple_legal_status: 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 PatSnap MCP Server. Nothing to install.
get_simple_legal_status 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_simple_legal_status 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_simple_legal_status. 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_simple_legal_status is provided by the PatSnap MCP Server MCP server (kunihiros/patsnap-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from PatSnap MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
