AI agents use feedback_pin to create or modify resources in Rag 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 feedback_pin 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 Rag Vault.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Register the Rag Vault MCP server in PolicyLayer and add a rule for feedback_pin: 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 Rag Vault. Nothing to install.
feedback_pin 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 feedback_pin 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 feedback_pin. 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.
feedback_pin is provided by the Rag Vault MCP server (@robthepcguy/rag-vault). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
