Set up the secrets vault for the first time. Returns 12 recovery words — store them safely. The vault stores credentials that agents can use without ever seeing the values.
AI agents use vault_setup to create or update resources in Kova Mind MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Kova Mind MCP Server environment.
This is classified as Write rather than Execute because it creates and configures a data structure (the vault) rather than executing arbitrary code or running external operations. However, severity is high because misconfiguring credential vaults or losing recovery words can compromise all stored secrets.
From the tool's definition The tool performs 'Set up the secrets vault for the first time' and 'Returns 12 recovery words — store them safely,' indicating it creates and initializes a new vault structure and generates cryptographic recovery material.
Attacks that exploit this kind of access
Set up the secrets vault for the first time. Returns 12 recovery words — store them safely. The vault stores credentials that agents can use without ever seeing the values. It is categorised as a Write tool in the Kova Mind MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Kova Mind MCP Server MCP server in PolicyLayer and add a rule for vault_setup: 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 Kova Mind MCP Server. Nothing to install.
vault_setup is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the vault_setup 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 vault_setup. 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.
vault_setup is provided by the Kova Mind MCP Server MCP server (kovamind/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
