[AIOBS] Search and filter AI agent sessions with multiple criteria including text search, labels, provider, model, function name, date range, errors, and failed evaluations.
AI agents call aiobs_search_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 filters observability data without modifying or deleting anything. It supports debugging and analysis workflows by retrieving session information based on multiple filter criteria. The blast radius of misuse is limited to potential exposure of monitoring/debugging data that would typically be accessible to authorized users anyway.
From the tool's definition Tool description explicitly states 'Search and filter AI agent sessions' with query criteria (text search, labels, provider, model, function name, date range, errors, evaluations).

[AIOBS] Search and filter AI agent sessions with multiple criteria including text search, labels, provider, model, function name, date range, errors, and failed evaluations. It is categorised as a Read tool in the Shepherd MCP MCP Server, which means it retrieves data without modifying state.
Register the Shepherd MCP server in PolicyLayer and add a rule for aiobs_search_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_search_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_search_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_search_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.
aiobs_search_sessions is provided by the Shepherd MCP server (neuralis-in/shepherd-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
