List notes (excerpt only). Use get_note for full content.
AI agents call list_notes to retrieve information from Rhizm MCP Server 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 note summaries without altering, creating, or destroying any data. It has no side effects and presents minimal risk if misused by an AI agent—at worst, it could retrieve sensitive information already stored in the system, but cannot modify or delete data. Severity is low given the read-only nature and limited blast radius.
From the tool's definition Tool name 'list_notes' and description 'List notes (excerpt only)' indicate data retrieval with no modification or deletion. The description explicitly directs users to 'get_note for full content', confirming this is a read-only operation.

Register the Rhizm MCP Server MCP server in PolicyLayer and add a rule for list_notes: 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 Rhizm MCP Server. Nothing to install.
list_notes 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_notes 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_notes. 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_notes is provided by the Rhizm MCP Server MCP server (rhizmapp/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
