What list_events does on Bugsink MCP Server

AI agents call list_events to retrieve information from Bugsink MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why list_events needs a policy

This tool retrieves and lists error event data from an error tracking system. It performs a read-only query operation ('list') that returns information without modifying, deleting, executing code, or affecting financial systems. The blast radius of misuse is minimal—an agent could retrieve error logs it may not be authorized to view, but cannot alter data or trigger external operations.

From the tool's definition Tool name 'list_events' and description 'List events (individual error occurrences) for a specific issue. Returns basic event info.' indicate a query operation with no side effects.

How to control list_events

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_events": {}
  }
}

list_events is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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