This verifier delegates token validation to a user-provided callable. By default, it accepts all non-empty tokens (useful for testing). Use cases: - Testing: Accept any token without real verification - Development: Custom validation logic for prototyping - Opaque tokens: When you have tokens with no introspection endpoint WARNING: This bypasses standard security checks. Only use in controlled environments or when you understand the security implications. cdS)NT)tokens /Users/kimhansen/Desktop/03 Workspace/ceo-agents/chl-effectiveness/mcp-servers/whoop/.venv/lib/python3.11/site-packages/fastmcp/server/auth/providers/debug.pyzDebugTokenVerifier.:s4z debug-clientNvalidate8Callable[[str], bool] | Callable[[str], Awaitable[bool]] client_idstrscopeslist[str] | Nonerequired_scopesczt|||_||_|pg|_dS)aInitialize the debug token verifier.
