sync_cache · QIT MCP Server MCP: Risk & Policy

WHAT IT DOES

What sync_cache does on QIT MCP Server

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

WHY IT NEEDS A POLICY

Why sync_cache needs a policy

Syncing/refreshing a local cache involves writing/updating local data to match the remote state. It's reversible (can be re-synced) and modifies local cache data rather than deleting it. No code execution or destructive behavior is implied.

Verdict

sync_cache Rate-limited

sync_cache 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.

FAQ

Questions about sync_cache

What does the sync_cache tool do? +

Re-sync local cache with QIT Manager. It is categorised as a Write tool in the QIT 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 sync_cache? +

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

What risk level is sync_cache? +

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

Can I rate-limit sync_cache? +

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

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

sync_cache is provided by the QIT MCP Server MCP server (woocommerce/qit-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
