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

These attack patterns abuse exactly the kind of access export_dpo_pairs gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Export DPO preference pairs from local memory log. It is categorised as a Write tool in the ThumbGate MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the ThumbGate MCP server in PolicyLayer and add a rule for export_dpo_pairs: 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 ThumbGate. Nothing to install.
export_dpo_pairs 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 export_dpo_pairs 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 export_dpo_pairs. 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.
export_dpo_pairs is provided by the ThumbGate MCP server (rlhf-loop/mcp-memory-gateway-v2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
