add_swift · CloudStack MCP Server MCP: Risk & Policy

WHAT IT DOES

What add_swift does on CloudStack MCP Server

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

WHY IT NEEDS A POLICY

Why add_swift needs a policy

This tool creates a new persistent configuration (adding a Swift image store backend), which is a reversible Write operation. It's not Destructive (no deletion or data loss), not Execute (no arbitrary code running), not Read (modifies rather than queries infrastructure).

From the tool's definition Tool name is 'add_swift' and description states 'Add OpenStack Swift as image store backend' — this creates/configures a new storage backend resource in the infrastructure.

Verdict

add_swift Rate-limited

add_swift 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches CloudStack MCP Server, so you can run agents against it safely.

FAQ

Questions about add_swift

What does the add_swift tool do? +

Add OpenStack Swift as image store backend. It is categorised as a Write tool in the CloudStack MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on add_swift? +

Register the CloudStack MCP Server MCP server in PolicyLayer and add a rule for add_swift: 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 CloudStack MCP Server. Nothing to install.

What risk level is add_swift? +

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

Can I rate-limit add_swift? +

Yes. Add a rate_limit block to the add_swift 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 add_swift completely? +

Set action: deny in the PolicyLayer policy for add_swift. 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 add_swift? +

add_swift is provided by the CloudStack MCP Server MCP server (mozg31337/cloudstack-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
