Assess the lucrativeness of a technology space based on the spread of estimated patent valuation (simple families). Higher value buckets indicate more lucrative technologies. Design patents are excluded. Note: Search must contain either keywords or IPC. If both are provided, IPC is prioritized.
AI agents call get_portfolio_value_distribution 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 reads patent valuation distribution data from PatSnap's API for analysis and reporting purposes. It queries and retrieves information about patent value buckets across a technology space without creating, modifying, deleting, or executing any operations. All sibling tools (get_most_cited_patents, get_top_inventors, etc.) follow the same read-only pattern.
From the tool's definition Tool name and description indicate data retrieval: 'Assess the lucrativeness' and 'spread of estimated patent valuation' are analytical queries that retrieve and analyze existing patent data.
Documented attack patterns abuse exactly the kind of access get_portfolio_value_distribution 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_portfolio_value_distribution:
{
"version": "1",
"default": "deny",
"tools": {
"get_portfolio_value_distribution": {}
}
}get_portfolio_value_distribution is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Assess the lucrativeness of a technology space based on the spread of estimated patent valuation (simple families). Higher value buckets indicate more lucrative technologies. Design patents are excluded. 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_portfolio_value_distribution: 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_portfolio_value_distribution 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_portfolio_value_distribution 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_portfolio_value_distribution. 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_portfolio_value_distribution 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.
Free to start. No card required.
