WHAT IT DOES

What export_migration does on Cloudera Data Visualization MCP Server

AI agents use export_migration to create or update resources in Cloudera Data Visualization MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Cloudera Data Visualization MCP Server environment.

WHY IT NEEDS A POLICY

Why export_migration needs a policy

An AI agent can call export_migration faster than any human can review — one bad instruction and it creates or modifies resources in Cloudera Data Visualization MCP Server by the hundred, each call as confident as the last.

Verdict

export_migration Rate-limited

export_migration stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about export_migration

What does the export_migration tool do? +

Export all CDV visual artifacts (dashboards, datasets, connections) as a migration bundle. It is categorised as a Write tool in the Cloudera Data Visualization MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on export_migration? +

Register the Cloudera Data Visualization MCP Server MCP server in PolicyLayer and add a rule for export_migration: 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 Cloudera Data Visualization MCP Server. Nothing to install.

What risk level is export_migration? +

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

Can I rate-limit export_migration? +

Yes. Add a rate_limit block to the export_migration 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.

How do I block export_migration completely? +

Set action: deny in the PolicyLayer policy for export_migration. 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 export_migration? +

export_migration is provided by the Cloudera Data Visualization MCP Server MCP server (kevintalbert/cdv-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
