AI agents use create_collection 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.
This tool creates a new collection (schema/table), which is a reversible Write operation. It does not execute arbitrary code, delete data, move funds, or cause irreversible damage. The blast radius is low as collections can be dropped and recreated; misconfiguration affects only the new collection being created.
From the tool's definition Tool description states 'Create a new collection in seekdb' and 'A collection is similar to a table in a database, used for storing vector data.' The tool creates new database structures (collections) with parameters for name, dimension, and distance metric.
Documented attack patterns abuse exactly the kind of access create_collection 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 create_collection:
{
"version": "1",
"default": "deny",
"tools": {
"create_collection": {
"limits": [
{
"counter": "create_collection_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_collection 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 collection in seekdb. A collection is similar to a table in a database, used for storing vector data. Args: collection_name: The name of the collection to be created. Must be unique within the database and no longer than 64 characters. dimension: The dimension of the vectors to be stored. Default is 384. distance: The distance metric for vector similarity. Options: 'cosine', 'l2', 'ip' (inner product). Default is 'l2'. Returns: A JSON string indicating success or error. 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 create_collection: 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.
create_collection 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 create_collection 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 create_collection. 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.
create_collection 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.
