AI agents use tool_entity_resolve to create or modify resources in Patent Space. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call tool_entity_resolve repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Patent Space.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Resolve a company name to its canonical form. Accepts names in any language/format. Uses 3-level matching: exact, normalized, and fuzzy. Args: query: Company name to resolve (any language). limit: Maximum results to return. Returns: List of matching entities with confidence scores.. It is categorised as a Write tool in the Patent Space MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Patent Space MCP server in PolicyLayer and add a rule for tool_entity_resolve: 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_entity_resolve is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the tool_entity_resolve 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_entity_resolve. 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_entity_resolve 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.
