List all service accounts
AI agents call list_service_accounts to retrieve information from Grafana 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 and displays existing service accounts without modifying, executing, or destructively affecting any resources. However, the severity is elevated to 'medium' rather than 'low' because service account enumeration can expose sensitive identity and credential infrastructure; an AI agent listing all service accounts could identify high-privilege accounts or reveal the scope of automation integrations…
From the tool's definition Tool name 'list_service_accounts' and description 'List all service accounts' indicate a query/retrieval operation with no side effects. The action is to enumerate service accounts, which is a read-only information disclosure operation.
Attacks that exploit this kind of access
List all service accounts. It is categorised as a Read tool in the Grafana MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Grafana MCP Server MCP server in PolicyLayer and add a rule for list_service_accounts: 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 Grafana MCP Server. Nothing to install.
list_service_accounts 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_service_accounts 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_service_accounts. 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_service_accounts is provided by the Grafana MCP Server MCP server (quanticsoul4772/grafana-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
