AI agents use change_tenant_password to create or update resources in Mcp Oceanbase — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Oceanbase environment.
Changing a password is a Write operation (modifies credentials reversibly, as a new password can be set again). However, it carries high severity because misuse by an AI agent could lock out legitimate users from a tenant, effectively causing a denial of access. Confidence is reduced because the description is empty, so the exact behavior is inferred from the name alone.
From the tool's definition Tool name: 'change_tenant_password' — implies modifying a tenant's password credential.
Documented attack patterns abuse exactly the kind of access change_tenant_password gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Oceanbase, and nothing reaches the server without passing your rules. This is the rule we recommend for change_tenant_password:
{
"version": "1",
"default": "deny",
"tools": {
"change_tenant_password": {
"limits": [
{
"counter": "change_tenant_password_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}change_tenant_password 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_tenant_password. It is categorised as a Write tool in the Mcp Oceanbase MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Oceanbase MCP server in PolicyLayer and add a rule for change_tenant_password: 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 Mcp Oceanbase. Nothing to install.
change_tenant_password 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 change_tenant_password 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 change_tenant_password. 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.
change_tenant_password is provided by the Mcp Oceanbase MCP server (oceanbase/awesome-oceanbase-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
