AI agents use vault.submit_guardian_vote to create or modify resources in Hive Vault. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call vault.submit_guardian_vote repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Hive Vault.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Submit a guardian yes/no vote on a pending recovery request. Called by authorized guardian agents. Includes ZK proof verification. Once 3-of-5 guardians approve, recovery proceeds automatically.. It is categorised as a Write tool in the Hive Vault MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Hive Vault MCP server in PolicyLayer and add a rule for vault.submit_guardian_vote: 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.submit_guardian_vote 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.submit_guardian_vote 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.submit_guardian_vote. 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.submit_guardian_vote 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.
