AI agents call oboe_list_items to retrieve information from Obo 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 session items in a read-only manner. There are no side effects, data modifications, or external operations triggered. The sorting parameter does not change this classification.
From the tool's definition Tool description states 'List all items in a session, sorted by priority_score descending.' The action is purely retrieval and querying of existing data with no modification, deletion, or execution of external operations.

List all items in a session, sorted by priority_score descending. It is categorised as a Read tool in the Obo MCP Server, which means it retrieves data without modifying state.
Register the Obo MCP server in PolicyLayer and add a rule for oboe_list_items: 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 Obo. Nothing to install.
oboe_list_items 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 oboe_list_items 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 oboe_list_items. 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.
oboe_list_items is provided by the Obo MCP server (warnes-innovations/oboe-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
