[AIOBS] List all AI agent sessions from Shepherd. Returns session metadata, labels, and event counts.
AI agents call aiobs_list_sessions to retrieve information from Shepherd MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns session metadata from an observability platform. It performs a read operation (list/retrieve) with no capability to modify, delete, or execute actions. The data returned is observability metadata used for debugging and analysis, posing minimal risk even if misused by an agent.
From the tool's definition Tool description states 'List all AI agent sessions' and 'Returns session metadata, labels, and event counts.' The verb 'List' and return of metadata indicate data retrieval without modification or side effects.

Register the Shepherd MCP server in PolicyLayer and add a rule for aiobs_list_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 Shepherd MCP. Nothing to install.
aiobs_list_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 aiobs_list_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 aiobs_list_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.
