AI agents use grafana_create_annotation to create or update resources in PilotOps MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your PilotOps MCP environment.
The tool creates new data (annotations) in Grafana, which is a reversible write operation. Annotations can be edited or deleted later. Severity is medium because misuse could clutter dashboards or create misleading incident markers that affect incident response workflows, but the effect is not destructive and does not directly impact monitored systems.
From the tool's definition Tool name is 'grafana_create_annotation'; the 'create_' prefix indicates data creation. Grafana annotations are metadata objects that mark events or notes on dashboards and are stored persistently.
Documented attack patterns abuse exactly the kind of access grafana_create_annotation gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and PilotOps MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for grafana_create_annotation:
{
"version": "1",
"default": "deny",
"tools": {
"grafana_create_annotation": {
"limits": [
{
"counter": "grafana_create_annotation_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}grafana_create_annotation 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.

grafana_create_annotation. It is categorised as a Write tool in the PilotOps MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the PilotOps MCP server in PolicyLayer and add a rule for grafana_create_annotation: 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 PilotOps MCP. Nothing to install.
grafana_create_annotation is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the grafana_create_annotation 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.
Set action: deny in the PolicyLayer policy for grafana_create_annotation. 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.
grafana_create_annotation is provided by the PilotOps MCP server (muhammedehab35/pilot_ops-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from PilotOps MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
