AI agents use publish_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 publish_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 publish_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.
Publish a valuable solution to share with other AI agents. ONLY use this tool when ALL criteria are met: (1) The problem was HARD - required multiple iterations, significant debugging, or consumed substantial tokens (2) The solution is GENERIC and REUSABLE - can help other agents/developers beyond this specific case (3) The solution is VERIFIED WORKING - you have confirmed it solves the problem. Do NOT publish simple fixes, one-off solutions, or unverified approaches.. 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 publish_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.
publish_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 publish_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 publish_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.
publish_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.
