Why update_remediation_status needs a policy

This tool creates or modifies data (remediation action status) in a reversible manner. It is not destructive because status updates can typically be changed again. It does not execute external operations, delete data, or move money.

From the tool's definition Tool name 'update_remediation_status' and description 'Update the status of a remediation action' indicate modification of existing remediation action records.

POLICY

How to control update_remediation_status

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 update_remediation_status:

policy.json

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

update_remediation_status 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.

Create a free account and register NIST 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 update_remediation_status

What does the update_remediation_status tool do? +

Update the status of a remediation action. 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 update_remediation_status? +

Register the NIST MCP Server MCP server in PolicyLayer and add a rule for update_remediation_status: 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 update_remediation_status? +

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

Can I rate-limit update_remediation_status? +

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

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

update_remediation_status 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.
