Medium Risk

Why create_remediation_action needs a policy

This is a Write operation—it creates new remediation action records in a NIST controls database or compliance system. The action is reversible (remediation actions can be deleted or updated) and produces side effects limited to data modification rather than code execution or destructive operations.

From the tool's definition Tool name 'create_remediation_action' and description 'Create a remediation action for a control' indicate the tool creates or modifies data by adding a new remediation action record to a compliance management system.

POLICY

How to control create_remediation_action

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_remediation_action": {
      "limits": [
        {
          "counter": "create_remediation_action_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_remediation_action 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about create_remediation_action

What does the create_remediation_action tool do? +

Create a remediation action for a control. It is categorised as a Write tool in the NIST 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 create_remediation_action? +

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

What risk level is create_remediation_action? +

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

Can I rate-limit create_remediation_action? +

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

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

create_remediation_action is provided by the NIST MCP Server MCP server (tnicholson/nist-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every NIST MCP Server tool call.

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