What describe does on Http
AI agents call describe to retrieve information from Http without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why describe is rated Low
The describe function queries and returns detailed information about existing Kubernetes resources. This is a non-destructive read operation with no side effects. It does not execute code, modify data, or trigger external operations - it simply retrieves and displays resource metadata and status.
From the tool's definition Tool name 'describe' and description states it 'Describes a Kubernetes resource with detailed information' - this is a retrieval/query operation that returns information without modifying or executing against the cluster.
Attacks that exploit this kind of access
The rule that runs describe safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Http, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For describe, this is the rule to start with:
describe is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Http, apply this rule, and every describe call is checked against it from then on.
Questions about describe
Describes a Kubernetes resource with detailed information. It is categorised as a Read tool in the Http MCP Server, which means it retrieves data without modifying state.
Register the Http MCP server in PolicyLayer and add a rule for describe: 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 Http. Nothing to install.
describe 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 describe 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 describe. 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.
describe is provided by the Http MCP server (@paretools/http). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
