WHAT IT DOES

What neuron_unblock_contact does on Neuron

AI agents use neuron_unblock_contact to create or update resources in Neuron, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Neuron environment.

Parameter	Type	Required	Description
`jid`	string	Yes	Contact JID or phone number to unblock
`channelId`	string	Yes	WhatsApp channel identifier (UUID)

Parameters from the server's own tool schema.

RISK

Why neuron_unblock_contact is rated Medium

Unblocking is a data modification operation that changes contact relationship state reversibly. It is not read-only (no retrieval of data), not destructive (the action is undoable by re-blocking), not execution of arbitrary code, and not financial.

From the tool's definition Tool performs 'Unblock a previously blocked WhatsApp contact', which modifies the contact's blocking status—a reversible state change to an existing contact record.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs neuron_unblock_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_unblock_contact, this is the rule to start with:

neuron_unblock_contact Rate-limited

neuron_unblock_contact 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.
