THE RISK

Why create_incident needs a policy

This tool creates new incident records in Grafana, which is a reversible data creation operation. It does not delete data (so not Destructive), does not execute arbitrary code (so not Execute), and does not involve financial transactions (so not Financial).

From the tool's definition Tool name 'create_incident' and description 'Create a new Grafana incident with the provided details' indicate creating/modifying data.

POLICY

How to control create_incident

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

policy.json

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

create_incident 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 Grafana FastMCP 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 create_incident

What does the create_incident tool do? +

Create a new Grafana incident with the provided details. It is categorised as a Write tool in the Grafana FastMCP 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_incident? +

Register the Grafana FastMCP Server MCP server in PolicyLayer and add a rule for create_incident: 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 Grafana FastMCP Server. Nothing to install.

What risk level is create_incident? +

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

Can I rate-limit create_incident? +

Yes. Add a rate_limit block to the create_incident 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_incident completely? +

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

create_incident is provided by the Grafana FastMCP Server MCP server (sandersouza/grafanafastmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Grafana FastMCP Server tool call.

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