Identify note pairs with high embedding similarity.
AI agents call find_duplicates 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 performs semantic analysis on existing vault data to surface similar notes. It has no side effects - it does not create, modify, delete, or execute any external operations. It is purely informational retrieval, falling clearly into the Read category. The severity is low because misuse would only return information about vault contents, with no capability to alter state or trigger external actions.
From the tool's definition Tool identifies and returns note pairs with high embedding similarity - a read-only operation that retrieves and analyzes existing data without modification.
Attacks that exploit this kind of access
Identify note pairs with high embedding similarity. 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 find_duplicates: 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.
find_duplicates 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 find_duplicates 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 find_duplicates. 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.
find_duplicates 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.
find_duplicates is one line of Neuro Vault's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
