Why delete_source is rated Critical
This tool permanently removes a workflow source, which cannot be undone. Deletion of data is irreversible and qualifies as destructive. The high severity reflects that an AI agent misusing this tool could remove critical workflow configurations, disrupting automation pipelines. Confidence is high because the description explicitly uses the word 'delete,' which unambiguously indicates destructive action.
From the tool's definition The tool name is 'delete_source' and the description states 'Delete a workflow source.' The verb 'delete' indicates irreversible removal of data.
Attacks that exploit this kind of access
The rule that runs delete_source safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Automagik Tools, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_source, this is the rule to start with:
delete_source is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Automagik Tools, apply this rule, and every delete_source call is checked against it from then on.
Questions about delete_source

delete_source is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_source 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 delete_source. 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.
delete_source is provided by the Automagik Tools MCP server (namastexlabs/automagik-tools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
