AI agents call get_similar_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 is a purely informational retrieval operation. It searches and returns existing note relationships without side effects. The function queries the vault's index and returns matching results, which is characteristic of a Read operation. No data is created, modified, or destroyed.
From the tool's definition Tool name is 'get_similar_notes' and description states it will 'Find related notes' without modifying any content. The operation retrieves and queries semantic relationships and wikilinks without creating, modifying, or deleting data.

Find related notes — both semantically similar and explicitly linked from this note via [[wikilinks]]. Pass a vault-relative POSIX path (e.g. 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 get_similar_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.
get_similar_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 get_similar_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 get_similar_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.
get_similar_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.
get_similar_notes 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.
