Create a new bucket in LiveStreaming using S3-style API. The bucket will be created at https://<bucket>.<endpoint_url>
AI agents use live_streaming_create_bucket to create or update resources in Qiniu MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Qiniu MCP Server environment.
Creating a bucket is a write operation as it creates a new cloud storage resource. The severity is medium rather than high because bucket creation itself is reversible (buckets can be deleted) and does not directly expose existing data or execute arbitrary code. However, it could enable an attacker to create many buckets as a denial-of-service vector or to stage further attacks.
From the tool's definition The tool name 'create_bucket' and description 'Create a new bucket in LiveStreaming' indicate it creates a new resource (bucket) in the Qiniu Cloud storage system. This is a write operation that adds a new entity.
Documented attack patterns abuse exactly the kind of access live_streaming_create_bucket gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Qiniu MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for live_streaming_create_bucket:
{
"version": "1",
"default": "deny",
"tools": {
"live_streaming_create_bucket": {
"limits": [
{
"counter": "live_streaming_create_bucket_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}live_streaming_create_bucket 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.

Create a new bucket in LiveStreaming using S3-style API. The bucket will be created at https://<bucket>.<endpoint_url>. It is categorised as a Write tool in the Qiniu MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Qiniu MCP Server MCP server in PolicyLayer and add a rule for live_streaming_create_bucket: 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 Qiniu MCP Server. Nothing to install.
live_streaming_create_bucket 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 live_streaming_create_bucket 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 live_streaming_create_bucket. 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.
live_streaming_create_bucket is provided by the Qiniu MCP Server MCP server (qiniu/qiniu-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
