AI agents use register to create or update resources in CC2CC — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CC2CC environment.
The tool modifies agent identity or registration state, which is a reversible write operation affecting this agent's configuration within the inter-agent communication system. Severity is medium because misconfiguration could disrupt agent-to-agent messaging but is not destructive or financial.
From the tool's definition Tool name is 'register' with description 'Change this agent', indicating modification of agent state or configuration.
Documented attack patterns abuse exactly the kind of access register gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and CC2CC, and nothing reaches the server without passing your rules. This is the rule we recommend for register:
{
"version": "1",
"default": "deny",
"tools": {
"register": {
"limits": [
{
"counter": "register_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}register stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Change this agent. It is categorised as a Write tool in the CC2CC MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the CC2CC MCP server in PolicyLayer and add a rule for register: 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 CC2CC. Nothing to install.
register 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 register 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 register. 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.
register is provided by the CC2CC MCP server (non4me/cc2cc). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from CC2CC, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
