THE RISK

Low Risk

Why snap needs a policy

With no description provided, the tool's behavior cannot be determined. The name 'snap' could refer to taking a snapshot (Write/Read), but given the server context of Git-powered memory with version control, it likely creates a snapshot/commit of current state (Write). However, confidence is very low due to lack of evidence. Defaulting to Other with low confidence until more information is available.

From the tool's definition Tool description is empty; only the name 'snap' is available, which is ambiguous.

POLICY

How to control snap

PolicyLayer is an MCP gateway — it sits between your AI agents and MemoV, and nothing reaches the server without passing your rules. This is the rule we recommend for snap:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "snap": {
      "limits": [
        {
          "counter": "snap_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

snap gets a rate cap, and everything else on the server is denied unless you say otherwise.

Create a free account and register MemoV — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about snap

What does the snap tool do? +

snap. It is categorised as a Other tool in the MemoV MCP Server, which means it performs auxiliary operations.

How do I enforce a policy on snap? +

Register the MemoV MCP server in PolicyLayer and add a rule for snap: 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 MemoV. Nothing to install.

What risk level is snap? +

snap is a Other tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit snap? +

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

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

snap is provided by the MemoV MCP server (memovai/memov). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every MemoV tool call.

Start from MemoV, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
