- Move getTestConfig() calls from module level to test execution time
- Add CI-specific debug logging to diagnose environment loading issues
- Add verification step in CI workflow to check .env.test availability
- Ensure environment variables are loaded before tests access config
The issue was that config was being accessed at module import time,
which could happen before the global setup runs in some CI environments.
- Updated default N8N_API_KEY to match test expectations
- Ensured test environment variables are properly set with defaults
- Fixed environment configuration test to work in CI
This resolves the final test failure in CI.

This commit implements the ability to extract n8n node source code through MCP:
Features:
- New MCP tools: get_node_source_code and list_available_nodes
- NodeSourceExtractor utility for file system access to n8n nodes
- Support for extracting any n8n node including AI Agent from @n8n/n8n-nodes-langchain
- Resource endpoint for accessing node source: nodes://source/{nodeType}
Testing:
- Docker test environment with mounted n8n node_modules
- Multiple test scripts for different scenarios
- Comprehensive test documentation
- Standalone MCP client test demonstrating full extraction flow
The implementation successfully demonstrates:
1. MCP server can access n8n's installed nodes
2. Source code can be extracted and returned to MCP clients
3. Full metadata including package info and file locations
4. Support for credential code extraction when available
