  title: Luciq MCP Server App Hangs Occurrences API
  description: The Luciq MCP Server is a remote Model Context Protocol server hosted at api.luciq.ai/api/mcp that exposes mobile observability data — applications, crashes, crash patterns, occurrences, app hangs, bugs, and store reviews — as agent-callable tools. This OpenAPI document models the underlying read operations the MCP tools route to so they can be discovered, governed, and reused outside of an MCP client. Transport in production is Streamable HTTP over HTTPS (TLS 1.2+); authentication is OAuth 2.0 with Dynamic Client Registration or a personal access token issued from the Luciq dashboard. Available on all Luciq plans with no extra setup.
