List Deployments in a cluster, optionally scoped to a namespace.
AI agents call list_deployments to retrieve information from Rancher MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves deployment information from a Kubernetes cluster without creating, modifying, or deleting resources. It is a pure read operation consistent with other list tools on the server (list_clusters, list_pods, list_namespaces). The optional namespace scoping is a filter parameter that does not change its read-only nature. Misuse poses minimal risk as it only exposes existing cluster state.
From the tool's definition Tool name 'list_deployments' and description 'List Deployments in a cluster' indicate a query/retrieval operation with no modification or execution of resources.
Attacks that exploit this kind of access
List Deployments in a cluster, optionally scoped to a namespace. It is categorised as a Read tool in the Rancher MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Rancher MCP Server MCP server in PolicyLayer and add a rule for list_deployments: 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 Rancher MCP Server. Nothing to install.
list_deployments is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_deployments 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 list_deployments. 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.
list_deployments is provided by the Rancher MCP Server MCP server (lokimcpuniverse/rancher-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
