AI agents invoke verify_code to trigger actions in Proxima. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
The name 'verify_code' implies running or analyzing code to check its correctness, which maps to Execute. However, the empty description significantly lowers confidence. In the context of an AI gateway server with coding capabilities, verification likely involves executing or interpreting code.
From the tool's definition Tool name 'verify_code' suggests code execution or analysis; description is empty and uninformative.
Documented attack patterns abuse exactly the kind of access verify_code gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Proxima, and nothing reaches the server without passing your rules. This is the rule we recommend for verify_code:
{
"version": "1",
"default": "deny",
"tools": {
"verify_code": {
"limits": [
{
"counter": "verify_code_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}verify_code stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

verify_code. It is categorised as a Execute tool in the Proxima MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Proxima MCP server in PolicyLayer and add a rule for verify_code: 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 Proxima. Nothing to install.
verify_code is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the verify_code 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 verify_code. 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.
verify_code is provided by the Proxima MCP server (zen4-bit/proxima). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
