AI agents call list_memories to retrieve information from Agent-Comm-Hub 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 memory data without modifying, deleting, or executing any operations. It is a straightforward read operation that returns information about stored memories. The scope filtering is a read-only parameter that does not alter any underlying data. No side effects, no irreversibility, and no external operations are triggered.
From the tool's definition Tool name is 'list_memories' and description indicates it 'lists accessible memories' (列出可访问的记忆列表) sorted by creation time in descending order, with optional filtering by scope. The verbs 'list' and 'filter' are query operations with no side effects.

Register the Agent-Comm-Hub MCP server in PolicyLayer and add a rule for list_memories: 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 Agent-Comm-Hub. Nothing to install.
list_memories 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_memories 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_memories. 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_memories is provided by the Agent-Comm-Hub MCP server (liuboacean/agent-comm-hub). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
