RECOMMENDED RULE

The rule that runs neuron_respond_approval 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_respond_approval, this is the rule to start with:

neuron_respond_approval Rate-limited

neuron_respond_approval 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.

FAQ

Questions about neuron_respond_approval

What does the neuron_respond_approval tool do? +

Approve or reject a pending approval programmatically — the decision surface for an authorized operator acting via MCP instead of replying on WhatsApp. Fires the configured callback and posts the outcome to the WhatsApp chat. Exactly-once: the first responder (here or on WhatsApp) wins; later responses return 410. Requires a bot API key. It is categorised as a Write tool in the Neuron MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does neuron_respond_approval accept? +

neuron_respond_approval accepts 5 parameters: apiKey, reason, decision, approvalId, responderName. Required: apiKey, decision, approvalId. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on neuron_respond_approval? +

Register the Neuron MCP server in PolicyLayer and add a rule for neuron_respond_approval: 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 Neuron. Nothing to install.

What risk level is neuron_respond_approval? +
