get_cluster
AI agents call get_cluster to retrieve information from Mcp Read Only Argocd without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves cluster information from Argo CD without side effects. The server's explicit read-only design, combined with the consistent pattern of get_* and list_* operations across all siblings, confirms this is a Read operation. The empty description lowers confidence slightly but the context is unambiguous.
From the tool's definition Tool is part of a 'read-only' server that provides 'read-only access' to Argo CD. All sibling tools are query/retrieval operations (get_*, list_*). Tool name 'get_cluster' indicates data retrieval with no modification.
Attacks that exploit this kind of access
get_cluster. It is categorised as a Read tool in the Mcp Read Only Argocd MCP Server, which means it retrieves data without modifying state.
Register the Mcp Read Only Argocd MCP server in PolicyLayer and add a rule for get_cluster: 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 Mcp Read Only Argocd. Nothing to install.
get_cluster 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 get_cluster 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 get_cluster. 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.
get_cluster is provided by the Mcp Read Only Argocd MCP server (lukleh/mcp-read-only-argocd). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
