What zaps_zapCommand does on Genesis
AI agents invoke zaps_zapCommand to trigger actions in Genesis. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
| Parameter | Type | Required | Description |
|---|---|---|---|
body | object | Yes | A Command, or a purpose command: INCR {key, delta?}; LPUSH {key, value}; RPOP/LLEN {key}; REMEMBER {key, fields}; RECALL {key, field_names?}. |
name | string | Yes | Zap name |
idempotency_key | string | — | Optional stable key; with it a retry returns the original result |
Parameters from the server's own tool schema.
Why zaps_zapCommand is rated High
zaps_zapCommand triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

The rule that runs zaps_zapCommand safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Genesis, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For zaps_zapCommand, this is the rule to start with:
zaps_zapCommand stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Genesis, apply this rule, and every zaps_zapCommand call is checked against it from then on.

zaps_zapCommand is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the zaps_zapCommand 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 zaps_zapCommand. 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.
zaps_zapCommand is provided by the Genesis MCP server (@onesi/genesis-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
