core.circuit_breaker

Circuit Breaker — protege contra fallos en cascada en llamadas externas.

Implementa el patrón Circuit Breaker para proveedores LLM: - CLOSED: operación normal, se envían requests - OPEN: demasiados fallos consecutivos, se rechazan requests inmediatamente - HALF_OPEN: timeout de recuperación expirado, se permite un request de prueba

Classes

CircuitBreaker dataclass

Circuit breaker para un proveedor externo.

Parameters:

Name Type Description Default
failure_threshold int

fallos consecutivos para abrir el circuito

 5
recovery_timeout float

segundos antes de intentar half-open

 30.0

core.cache_manager

Prompt Cache Manager — multi-provider cache abstraction.

DeepSeek (now): Automatic server-side disk caching. No client API needed. We monitor cache hit/miss via response.usage fields.

Anthropic (future): Client-controlled ephemeral caching via cache_control markers. We inject {"type": "ephemeral"} on system/tools messages.

OpenAI (future): Automatic prompt caching (newer models). Monitor like DeepSeek.

Design
  • CacheManager is a singleton that accumulates per-workspace cache stats.
  • track_usage() extracts prompt_cache_hit_tokens / prompt_cache_miss_tokens from any provider response.
  • get_stats() returns hit rate and token savings for reporting.
  • stabilize_messages() is a helper that keeps the message prefix intact (critical for DeepSeek's prefix-based disk caching).

Functions

core.mcp.server

MCP server — expose Morphix tools over stdio JSON-RPC.

Usage

morphix mcp-server poetry run python -m core.mcp.server

Other MCP clients (opencode, Claude Desktop) can connect and use Morphix tools: file_manager, bash_manager, web_search, etc.

core.security.anti_distillation

Anti-distillation hardening — watermark rotation, pattern detection, escalation.

Companion to undercover_mode.py. Provides: 1. Watermark rotation — 8 styles, rotated per workspace+time seed 2. Query similarity tracking — detects N similar queries (extraction pattern) 3. Escalation levels — warn → throttle → honeypot → lock 4. Honeypot generator — fake system prompts to waste attackers
