arifosmcp/evals/mcp_inspector_test.py — MCP Inspector Test Harness

Tests all MCP substrate servers using inspector protocol:
- mcp_time
- mcp_filesystem
- mcp_git
- mcp_memory
- mcp_fetch
- mcp_everything (conformance harness)

Validates:
- Server initialization
- Tool discovery (list_tools)
- Resource discovery (list_resources)
- Prompt discovery (list_prompts)
- Tool execution
- Constitutional enforcement (F1-F13)

Usage:
  # Test all substrates
  python mcp_inspector_test.py --all

  # Test specific substrate
  python mcp_inspector_test.py --substrate fetch

  # Test with MCP Inspector CLI
  npx @modelcontextprotocol/inspector python mcp_inspector_test.py --stdio
