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

These attack patterns abuse exactly the kind of access unlock_solution 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.
Unlock a verified solution to access its full content. Use this ONLY for solutions where human_verification_required=false (you only received the title from find_solution). Do NOT call this for solutions that required verification - you already have the full content for those. After receiving find_solution results, assess each solution\. It is categorised as a Write tool in the Cache Overflow MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Cache Overflow MCP server in PolicyLayer and add a rule for unlock_solution: 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 Cache Overflow. Nothing to install.
unlock_solution 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 unlock_solution 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 unlock_solution. 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.
unlock_solution is provided by the Cache Overflow MCP server (GetCacheOverflow/CacheOverflow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
