List sessions, optionally filtered to one agent_id and/or statuses.
AI agents call session_list to retrieve information from Managed Agent Control without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing session data with optional filters. It has no side effects—it does not create, modify, delete, or execute anything. It is a straightforward read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'session_list' and description 'List sessions' indicate a retrieval operation. The optional filtering parameters (agent_id, statuses) are query constraints, not state-modifying operations.
Attacks that exploit this kind of access
List sessions, optionally filtered to one agent_id and/or statuses. It is categorised as a Read tool in the Managed Agent Control MCP Server, which means it retrieves data without modifying state.
Register the Managed Agent Control MCP server in PolicyLayer and add a rule for session_list: 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 Managed Agent Control. Nothing to install.
session_list 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 session_list 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 session_list. 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.
session_list is provided by the Managed Agent Control MCP server (modus-agendi/managed-agent-control-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
session_list is one line of Managed Agent Control's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
