Returns a single snapshot of vault structure: top-level folders with note counts, top tags, frontmatter properties, total note count, and the top 10 notes by inbound wikilinks. Call this once at the start of a session to orient yourself before reaching for. 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_vault_overview: 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_vault_overview 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_vault_overview 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_vault_overview. 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_vault_overview 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.
