WHEN AI AGENTS USE THIS TOOL

AI agents use add_structured_properties to create or modify resources in DataHub. 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.

WHY ENFORCE A POLICY ON ADD_STRUCTURED_PROPERTIES

Without a policy, an AI agent could call add_structured_properties repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach DataHub.

RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

FREQUENTLY ASKED QUESTIONS

What does the add_structured_properties tool do?

Manage structured properties on entities. It is categorised as a Write tool in the DataHub MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on add_structured_properties?

Add a rule in your Intercept YAML policy under the tools section for add_structured_properties. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the DataHub MCP server.

What risk level is add_structured_properties?

add_structured_properties is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit add_structured_properties?

Yes. Add a rate_limit block to the add_structured_properties rule in your Intercept 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.

How do I block add_structured_properties completely?

Set action: deny in the Intercept policy for add_structured_properties. 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.

What MCP server provides add_structured_properties?

add_structured_properties is provided by the DataHub MCP server (mcp-server-datahub). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
