sample_dataset · MCP DS Toolkit Server MCP: Risk & Policy

WHAT IT DOES

What sample_dataset does on MCP DS Toolkit Server

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

WHY IT NEEDS A POLICY

Why sample_dataset needs a policy

This tool creates a new sample dataset, which is a reversible write operation. It does not delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or merely read existing data (Read). The operation produces a derived artifact that can be modified or discarded without permanent consequences.

From the tool's definition Tool name 'sample_dataset' and description 'Create a sample from a dataset' indicate creation of new data (a subset/sample) derived from existing data. The verb 'Create' is a write operation.

Verdict

sample_dataset Rate-limited

sample_dataset 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 sample_dataset

What does the sample_dataset tool do? +

Create a sample from a dataset. It is categorised as a Write tool in the MCP DS Toolkit 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 sample_dataset? +

Register the MCP DS Toolkit Server MCP server in PolicyLayer and add a rule for sample_dataset: 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 MCP DS Toolkit Server. Nothing to install.

What risk level is sample_dataset? +

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

Can I rate-limit sample_dataset? +

Yes. Add a rate_limit block to the sample_dataset 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 sample_dataset completely? +

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

sample_dataset is provided by the MCP DS Toolkit Server MCP server (yasserelhaddar/mcp-ds-toolkit-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
