WHAT IT DOES

What notifications does on Open Stocks MCP

AI agents call notifications to retrieve information from Open Stocks MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why notifications is rated Low

This tool retrieves notifications and alerts associated with an account, which is purely informational and has no side effects. No data is created, modified, deleted, or executed. The information exposed (alerts/notifications) is typically non-sensitive operational metadata. This is the lowest-risk category.

From the tool's definition Tool name 'notifications' and description 'Gets account notifications and alerts' indicate a retrieval operation with no modifications. The verb 'Gets' confirms read-only functionality.

RECOMMENDED RULE

The rule that runs notifications safely

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

notifications Allowed

notifications is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "notifications": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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