List all active ACM sessions.
AI agents call list_acm_sessions to retrieve information from ACM MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that retrieves session metadata. It has no side effects, does not modify data, execute code conditionally, delete resources, or commit financial actions. The blast radius of misuse is minimal—an attacker could only discover which ACM sessions are active, which is low-impact reconnaissance information.
From the tool's definition Tool name 'list_acm_sessions' and description 'List all active ACM sessions' indicate a query operation that retrieves information about running sessions without modifying state.
Attacks that exploit this kind of access
List all active ACM sessions. It is categorised as a Read tool in the ACM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ACM MCP Server MCP server in PolicyLayer and add a rule for list_acm_sessions: 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 ACM MCP Server. Nothing to install.
list_acm_sessions 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_acm_sessions 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_acm_sessions. 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_acm_sessions is provided by the ACM MCP Server MCP server (pekosann/acm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
