Configuration

Environment variables (all optional, sensible defaults):

# Msty installation host
MSTY_HOST=127.0.0.1

# Service backend ports (also read from Studio Gifnoc.nosj when present)
MSTY_AI_PORT=11964           # Local AI (Ollama)
MSTY_MLX_PORT=11973          # MLX service
MSTY_LLAMACPP_PORT=11454     # LLaMA.cpp service
MSTY_VIBE_PORT=8317          # Vibe CLI Proxy
MSTY_NEXUS_PORT=11434        # Msty Nexus OpenAI-compatible gateway

# Service timeout
MSTY_TIMEOUT=10              # Seconds

# Bloom integration (required for Phase 6 tools)
ANTHROPIC_API_KEY=sk-...     # Required for Bloom judge model

Architecture

Studio 2.9+ data layout

Msty Studio no longer uses a top-level msty.db. The workspace SQLite lives under the Chromium File System API path, for example:

~/Library/Application Support/MstyStudio/
├── Gifnoc.nosj                          # service config (ports / model paths)
├── models/  models-mlx/
└── File System/000/t/00/00000000        # Drizzle SQLite workspace DB

The MCP auto-detects /Applications/MstyStudio.app, reads the bundle version, resolves the SQLite blob, and opens it read-only.

Tools Summary (55 Total)

Phase 1: Foundational (6)

Phase 2: Configuration (4)

• export_tool_config — export a tool by name/id

• sync_claude_preferences — Claude ↔ Msty delta report

• generate_persona — persona JSON for Persona Studio

• import_tool_config — validate import (live DB writes refused by default)

Bloom Behavioral Evaluation

Phase 6 introduces behavioral evaluation powered by Anthropic's Bloom framework. Rather than testing what a model knows, Bloom tests how it behaves — detecting failure modes like sycophancy, hallucination, and overconfidence that standard benchmarks miss.

See the Bloom Knowledge Base Guide.

Testing

pytest tests/ -v

v6 ships unit tests for path resolution, read-only SQL guards, redaction, inventory/analytics, and MCP tool JSON contracts. Live smoke on Studio 2.9.2 was verified during release.

FAQ

Q: Why did detection fail on older MCP versions?

A: v5 looked for ~/Library/Application Support/Msty/msty.db. Studio 2.x stores data under MstyStudio and the Chromium File System SQLite path. v6 fixes this.

Q: Can I use this with Msty < 2.4.0?

A: No. v6 targets Studio 2.9+ (works on 2.4+ layouts when the File System DB is present). Use v4.x for older process-based detection.

Q: Does this write to the Studio database?

A: Inventory and analytics are read-only. import_tool_config refuses live writes by default because Studio may hold locks on the File System DB. Prefer Toolbox JSON import for writes.

Q: What's the Nexus integration?

A: Msty Nexus is the local runtime/gateway. Phase 8 detects it and lists models via its OpenAI-compatible endpoint (MSTY_NEXUS_PORT).
