List configured cluster aliases from clusters.yaml configuration.
AI agents call acp_list_clusters to retrieve information from Ambient Code Platform 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 cluster configuration information without modifying, deleting, or executing operations. It performs a straightforward query of existing configuration data, fitting the 'Read' category. Severity is low because exposure of cluster alias names has limited immediate impact, though it could inform reconnaissance in a multi-tenancy environment.
From the tool's definition Tool name is 'acp_list_clusters' and description states it 'List configured cluster aliases from clusters.yaml configuration.' The verb 'list' and the read-only nature of querying configuration data indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
List configured cluster aliases from clusters.yaml configuration. It is categorised as a Read tool in the Ambient Code Platform MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Ambient Code Platform MCP Server MCP server in PolicyLayer and add a rule for acp_list_clusters: 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 Ambient Code Platform MCP Server. Nothing to install.
acp_list_clusters 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 acp_list_clusters 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 acp_list_clusters. 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.
acp_list_clusters is provided by the Ambient Code Platform MCP Server MCP server (jeremyeder/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
