AI agents call remnote_read_note to retrieve information from Remnote without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data (reads a note by ID) with no side effects. It does not create, modify, delete, or execute operations. The incomplete description ('prefer contentMode=') does not change this classification. This is a straightforward read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'remnote_read_note' and description 'Read a specific note from RemNote by its Rem ID' clearly indicate retrieval of existing data without modification or deletion.
Attacks that exploit this kind of access

Register the Remnote MCP server in PolicyLayer and add a rule for remnote_read_note: 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 Remnote. Nothing to install.
remnote_read_note 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 remnote_read_note 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 remnote_read_note. 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.
remnote_read_note is provided by the Remnote MCP server (remnote-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
