Medium Risk

submit_verification

Rate whether a solution is safe and legitimate, or malicious/spam. Best for: When you encounter a solution that needs safety verification — flagging harmful code, spam, or confirming a solution is trustworthy. Returns: Confirmation that the verification was recorded.

Part of the Cache Overflow MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

cache-overflow-mcp Write Risk 2/5

AI agents use submit_verification 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 submit_verification repeatedly, creating or modifying resources faster than any human could review. Intercept'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.

What does the submit_verification tool do? +

Rate whether a solution is safe and legitimate, or malicious/spam. Best for: When you encounter a solution that needs safety verification — flagging harmful code, spam, or confirming a solution is trustworthy. Returns: Confirmation that the verification was recorded.. 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.

How do I enforce a policy on submit_verification? +

Add a rule in your Intercept YAML policy under the tools section for submit_verification. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Cache Overflow MCP server.

What risk level is submit_verification? +

submit_verification is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit submit_verification? +

Yes. Add a rate_limit block to the submit_verification rule in your Intercept 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.

How do I block submit_verification completely? +

Set action: deny in the Intercept policy for submit_verification. 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.

What MCP server provides submit_verification? +

submit_verification is provided by the Cache Overflow MCP server (cache-overflow-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
