"""
Comprehensive integration tests for MCP (Model Context Protocol) Service.

Tests cover:
- Server lifecycle (start, stop, restart)
- Tool discovery and listing
- Tool execution with various argument types
- JSON-RPC message handling
- Schema validation for requests/responses
- Error handling (invalid tools, timeouts, connection failures)
- Configuration management
- Web search functionality
- BYOK integration for search API keys
- HITL (Human-in-the-Loop) policy checking

Coverage Target: 80%+ for integrations/mcp_service.py (2,468 lines)
Test Count: 35-40 tests
