AI agents use register to create or update resources in Openaaas Mcp Adapter — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Openaaas Mcp Adapter environment.
Registration creates new user account records and generates an API key credential. This is a Write operation (creates data reversibly) rather than Execute or Destructive, as account registration and key generation are standard reversible administrative operations. Severity is medium because misuse could create unauthorized accounts or keys, but the action itself is not inherently destructive or financial.
From the tool's definition Tool description states '注册客户端账号，获取 api_key' which translates to 'Register client account, obtain api_key'. This creates a new account and generates credentials, which is a reversible data creation action.
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 Openaaas Mcp Adapter, 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.

注册客户端账号，获取 api_key（仅需一次）. It is categorised as a Write tool in the Openaaas Mcp Adapter MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Openaaas Mcp Adapter 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 Openaaas Mcp Adapter. 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 Openaaas Mcp Adapter MCP server (wolido/openaaas). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Openaaas Mcp Adapter, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
