WHAT IT DOES

What shells_listShells does on Genesis

AI agents call shells_listShells to retrieve information from Genesis without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`include`	string	—	`ended` also lists ended Shells (`cancelled`, `terminated`, `failed` or `succeeded`; `orphaned` counts as active). Omit it to list live Shells only.

Parameters from the server's own tool schema.

RISK

Why shells_listShells is rated Low

Even though shells_listShells only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

RECOMMENDED RULE

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

shells_listShells Allowed

shells_listShells is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Genesis, apply this rule, and every shells_listShells call is checked against it from then on.
