AI agents call mindmap_list to retrieve information from Mindmap 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 stored memory data without side effects. It does not create, modify, delete, or execute operations—only lists existing memories with optional filtering.
From the tool's definition Tool name 'mindmap_list' and description explicitly states 'Read-only' and 'List saved memories with optional filters'. Returns a list of memories with no modification or deletion capability.
Attacks that exploit this kind of access
List saved memories with optional filters, newest-used first. Read-only. Args: source/tag/tier filters, include_archived (default false), limit (default 20). Returns: list of memories. It is categorised as a Read tool in the Mindmap MCP Server, which means it retrieves data without modifying state.
Register the Mindmap MCP server in PolicyLayer and add a rule for mindmap_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 Mindmap. Nothing to install.
mindmap_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 mindmap_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 mindmap_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.
mindmap_list is provided by the Mindmap MCP server (@ravi-labs/mindmap-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
