Update an annotation layer. Pass only the fields to change.
AI agents use superset_annotation_layer_update to create or update resources in MCP Superset — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Superset environment.
The tool modifies annotation layer data reversibly. It is not destructive (no deletion), not financial, and not an execute operation that runs arbitrary code. While it changes data, the scope is limited to annotation layers in a data visualization tool.
From the tool's definition Tool name contains 'update' and description states 'Update an annotation layer. Pass only the fields to change.' This indicates modification of existing data.
Documented attack patterns abuse exactly the kind of access superset_annotation_layer_update gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Superset, and nothing reaches the server without passing your rules. This is the rule we recommend for superset_annotation_layer_update:
{
"version": "1",
"default": "deny",
"tools": {
"superset_annotation_layer_update": {
"limits": [
{
"counter": "superset_annotation_layer_update_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}superset_annotation_layer_update 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.

Update an annotation layer. Pass only the fields to change. It is categorised as a Write tool in the MCP Superset MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the MCP Superset MCP server in PolicyLayer and add a rule for superset_annotation_layer_update: 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 MCP Superset. Nothing to install.
superset_annotation_layer_update 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 superset_annotation_layer_update 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 superset_annotation_layer_update. 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.
superset_annotation_layer_update is provided by the MCP Superset MCP server (mcp-superset). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Superset, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
