WHAT IT DOES

What create_collection does on ProAgentStore

AI agents use create_collection to create or update resources in ProAgentStore, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ProAgentStore environment.

RISK

Why create_collection is rated Medium

The tool creates new collections (data structures) for an agent, which is a Write operation as it creates and modifies data reversibly. The severity is medium rather than high because collection creation is typically reversible (collections can be deleted) and doesn't directly affect existing production data or have cross-system financial implications.

From the tool's definition Tool description states 'Create a new data collection' which is a create operation that adds new data structures. The tool allows defining fields and indexing, indicating it modifies the agent's data schema in a reversible manner.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_collection safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ProAgentStore, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_collection, this is the rule to start with:

create_collection Rate-limited

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.

The button opens the PolicyLayer dashboard: create your workspace, connect ProAgentStore, apply this rule, and every create_collection call is checked against it from then on.

How do I enforce a policy on create_collection? +

Register the ProAgentStore 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 ProAgentStore. Nothing to install.

What risk level is create_collection? +

create_collection is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_collection? +

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.

How do I block create_collection completely? +

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.

What MCP server provides create_collection? +

create_collection is provided by the ProAgentStore MCP server (https://mcp.proagentstore.online/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
