What c4_codegen does on C4REQBER
AI agents invoke c4_codegen to trigger actions in C4REQBER. 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.
Why c4_codegen is rated High
The name 'c4_codegen' strongly implies code generation functionality, which typically falls under Execute as it produces and potentially runs code. However, with an empty description, confidence is reduced. The server context mentions 'formal verification' and '21 MCP tools' for a cognitive exoskeleton system, suggesting this tool generates code artifacts.
From the tool's definition Tool name 'c4_codegen' suggests code generation; description is empty and uninformative.
Attacks that exploit this kind of access
The rule that runs c4_codegen safely
PolicyLayer is an MCP gateway: it sits between your AI agents and C4REQBER, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For c4_codegen, this is the rule to start with:
c4_codegen 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.
The button opens the PolicyLayer dashboard: create your workspace, connect C4REQBER, apply this rule, and every c4_codegen call is checked against it from then on.
Questions about c4_codegen
c4_codegen is a execute tool on the C4REQBER MCP server. It is categorised as a Execute tool in the C4REQBER MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the C4REQBER MCP server in PolicyLayer and add a rule for c4_codegen: 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 C4REQBER. Nothing to install.
c4_codegen 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 c4_codegen 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 c4_codegen. 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.
c4_codegen is provided by the C4REQBER MCP server (C4MIND/C4REQBER). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
