AI agents call list-parameters-component-vhost to retrieve information from Rabbitmq without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
vhost | string | Yes | |
component | string | Yes |
Parameters from the server's own tool schema.
This tool retrieves and displays parameters without creating, modifying, deleting, or executing any operations. It is a straightforward read-only query operation on RabbitMQ configuration metadata. The blast radius of misuse is minimal — an attacker gains visibility into vhost parameter configuration but cannot alter system state or trigger side effects.
From the tool's definition Tool name contains 'list' and description states 'List all parameters for a given component in a vhost' — a query operation with no modification or deletion of data.
Attacks that exploit this kind of access
List all parameters for a given component in a vhost. It is categorised as a Read tool in the Rabbitmq MCP Server, which means it retrieves data without modifying state.
list-parameters-component-vhost accepts 2 parameters: vhost, component. Required: vhost, component. The full parameter table on this page comes from the server's own tool schema.
Register the Rabbitmq MCP server in PolicyLayer and add a rule for list-parameters-component-vhost: 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 Rabbitmq. Nothing to install.
list-parameters-component-vhost 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-parameters-component-vhost 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-parameters-component-vhost. 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-parameters-component-vhost is provided by the Rabbitmq MCP server (rabbitmq-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
