Read one or more notes in one call.
AI agents call read_notes to retrieve information from Neuro Vault without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing note data from an Obsidian vault without creating, modifying, deleting, or executing any operations. It is a straightforward query function that poses minimal risk—the primary concern would be unauthorized access to sensitive note contents, but the tool itself cannot cause data loss or unwanted modifications.
From the tool's definition Tool name is 'read_notes' and description states 'Read one or more notes in one call.' The verb 'Read' and the operation of retrieving note contents are unambiguous indicators of a read-only retrieval action with no side effects.
Attacks that exploit this kind of access
Read one or more notes in one call. It is categorised as a Read tool in the Neuro Vault MCP Server, which means it retrieves data without modifying state.
Register the Neuro Vault MCP server in PolicyLayer and add a rule for read_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 Neuro Vault. Nothing to install.
read_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 read_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 read_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.
read_notes is provided by the Neuro Vault MCP server (neuro-vault-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
