update_description
Update or remove descriptions for entities or fields
Part of the DataHub MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
WHEN AI AGENTS USE THIS TOOL
AI agents use update_description 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 UPDATE_DESCRIPTION
Without a policy, an AI agent could call update_description 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 update_description tool do?
Update or remove descriptions for entities or fields. 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 update_description?
Add a rule in your Intercept YAML policy under the tools section for update_description. 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 update_description?
update_description is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Can I rate-limit update_description?
Yes. Add a rate_limit block to the update_description 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 update_description completely?
Set action: deny in the Intercept policy for update_description. 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 update_description?
update_description 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.
