AI agents use update_profile 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.
This tool modifies user profile information (username) reversibly. It is a Write operation that changes data state but does not irreversibly delete data or execute arbitrary code. Severity is medium because unauthorized username changes could lead to account confusion, impersonation risks, or access control issues, but impact is scoped to profile metadata rather than system-wide operations.
From the tool's definition Tool name 'update_profile' combined with description '修改当前客户端用户名' (modify current client username) indicates creation or modification of user profile data.
Documented attack patterns abuse exactly the kind of access update_profile 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 update_profile:
{
"version": "1",
"default": "deny",
"tools": {
"update_profile": {
"limits": [
{
"counter": "update_profile_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_profile 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.

修改当前客户端用户名. 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 update_profile: 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.
update_profile 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 update_profile 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 update_profile. 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.
update_profile 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.
