Why neuron_delete_contact is rated Critical
This tool irreversibly deletes data (contact records) and cannot be reversed. While the blast radius is limited to a single contact record rather than an entire database, the permanent nature and inability to undo the action places it in the Destructive category with high severity. An AI agent could inadvertently delete important contacts if given improper instructions or access.
From the tool's definition The description explicitly states 'Permanently delete a contact and remove them from all contact lists. This action cannot be undone.' The use of 'Permanently delete' and 'cannot be undone' are definitive markers of destructive operations.
Attacks that exploit this kind of access
The rule that runs neuron_delete_contact safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Neuron, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For neuron_delete_contact, this is the rule to start with:
neuron_delete_contact 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 Neuron, apply this rule, and every neuron_delete_contact call is checked against it from then on.
