Why distribution_operation needs a policy

This tool runs SageMath computations for probability distributions including sampling (executing random variate generation). While most operations are read/query-like (PDF, CDF, mean, variance), sampling involves executing code that produces side effects via the persistent SageMath session.

From the tool's definition 'Probability distribution operations: PDF, CDF, quantile, mean, variance, sampling' — 'sampling' implies executing random number generation or computational operations through SageMath

POLICY

How to control distribution_operation

PolicyLayer is an MCP gateway — it sits between your AI agents and SageMath MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for distribution_operation:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "distribution_operation": {
      "limits": [
        {
          "counter": "distribution_operation_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

distribution_operation stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register SageMath MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about distribution_operation

What does the distribution_operation tool do? +

Probability distribution operations: PDF, CDF, quantile, mean, variance, sampling. It is categorised as a Execute tool in the SageMath MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on distribution_operation? +

Register the SageMath MCP Server MCP server in PolicyLayer and add a rule for distribution_operation: 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 SageMath MCP Server. Nothing to install.

What risk level is distribution_operation? +

distribution_operation is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit distribution_operation? +

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

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

distribution_operation is provided by the SageMath MCP Server MCP server (xbp-europe/sagemath-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every SageMath MCP Server tool call.

Start from SageMath MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
