AI agents call tool_tech_fit to retrieve information from Patent Space without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though tool_tech_fit only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Compute phi_tech fit components for a firm and technology cluster. Measures how well a firm's patent portfolio aligns with a technology cluster. Returns CPC overlap ratio, citation proximity, co-inventor score, and combined phi_tech score. Args: firm_query: Company name (any language), stock ticker, or firm_id. tech_query_or_cluster_id: Cluster ID (e.g., "H01M_0", "G06N_0") or CPC code (e.g., "H01M"). Use tech_clusters_list to browse available clusters. year: Analysis year (default: 2024). Available: 2016-2024. Returns: Dict with phi_tech score and component breakdown (cpc_overlap, citation_proximity, co_inventor, combined).. It is categorised as a Read tool in the Patent Space MCP Server, which means it retrieves data without modifying state.
Register the Patent Space MCP server in PolicyLayer and add a rule for tool_tech_fit: 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 Patent Space. Nothing to install.
tool_tech_fit 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 tool_tech_fit 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 tool_tech_fit. 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.
tool_tech_fit is provided by the Patent Space MCP server (Rei02061986/patent-space-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
