Get full content of a note by UUID.
AI agents call read_note to retrieve information from Streamline MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves note content by identifier without modifying, deleting, or executing any operations. It is a straightforward query operation that fits the Read category. Severity is low because retrieving note data poses minimal risk even if misused by an AI agent—at worst it exposes the content of notes the user already has access to.
From the tool's definition Tool name 'read_note' and description 'Get full content of a note by UUID' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Get full content of a note by UUID. It is categorised as a Read tool in the Streamline MCP MCP Server, which means it retrieves data without modifying state.
Register the Streamline MCP server in PolicyLayer and add a rule for 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 Streamline MCP. Nothing to install.
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 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 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.
read_note is provided by the Streamline MCP server (rostehea/streamline-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
