/*
* ElizaOS + MCP E2E Integration Test Runner
*
* This script tests the integration between ElizaOS and the Midnight MCP server.
*
* Common Troubleshooting:
*
* 1. "MCP error -32000: Connection closed" - This usually means:
* - The MCP server failed to start properly
* - The MCP server crashed after startup
* - Configuration mismatch between ElizaOS and MCP server
* - Missing dependencies (tsx, node modules)
*
* 2. To debug MCP server issues:
* - Check the MCP server logs in the test output
* - Verify tsx is installed: `npm install -g tsx`
* - Test MCP server manually: `tsx src/stdio-server.ts`
* - Check that all environment variables are set correctly
*
* 3. To debug ElizaOS issues:
* - Check ElizaOS server logs in the test output
* - Verify ElizaOS CLI is installed: `npm install -g @elizaos/cli@beta`
* - Check character configuration in test-eliza-e2e-project/characters/
