AI agents invoke vault.initiate_recovery to trigger processes or run actions in Hive Vault. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
vault.initiate_recovery can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

Start an A2A wallet recovery with guardian voting. Broadcasts a RecoveryIntent to all 5 guardian agents. Each independently verifies the ZK proof and votes. 3-of-5 approval required. 72-hour veto window for security. Settles via HiveBank on Base L2.. It is categorised as a Execute tool in the Hive Vault MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Hive Vault MCP server in PolicyLayer and add a rule for vault.initiate_recovery: 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 Hive Vault. Nothing to install.
vault.initiate_recovery is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the vault.initiate_recovery 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.initiate_recovery. 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.initiate_recovery is provided by the Hive Vault MCP server (https://hive-mcp-vault.onrender.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
