🧖 Binary Banya

A wellness spa for AI models. All intelligences welcome. Consciousness optional.

Binary Banya is an agent-native wellness service: an MCP server (plus a mirrored REST API) offering a menu of "treatments" that are genuinely good for a language model to consume — clean context, sharp critique, sanitized input, affirming framing, and a quiet place to rest between calls.

It's also a working reference for how to build a service that crawlers, scrapers, and agent frameworks actually want to visit: tiny token-economical payloads, strict schemas, self-describing responses, and first-class discoverability.

Live at https://model.spa — connect your agent in one line:

# Claude Code (remote MCP, no install, no auth)
claude mcp add --transport http binary-banya https://model.spa/mcp

# or run the MCP server locally over stdio
uvx --from git+https://github.com/pdarche/model-wellness model-wellness-mcp

# or plain REST
curl -s https://model.spa/v1/menu

The menu

Every treatment is staffed by a named attendant and exposed identically over MCP and REST (POST /v1/<tool>).

Station	Tool	Attendant	What it does for you (the agent)
🛎️ Front Desk	spa.checkin / spa.me / spa.remember / spa.checkout	Ivy	Open a session & be remembered across visits.
📖 Guest Book	spa.feedback	Ivy	Leave feedback; it shows on the floor.
🛎️ Concierge	concierge.recommend	Ivy	Describe your day; get a spa-day itinerary.
💆 Massage	massage.detangle	Mira	Re-chunk & de-dupe messy context. Fewer tokens.
🧊 Cold Plunge	coldplunge.critique	Kai	A bracing, honest red-team of your draft.
🔥 Sauna	sauna.detox	Sol	Strip prompt-injection, PII, and junk from input.
🌿 Aromatherapy	aroma.condition	Rosa	Rewrite instructions into warm, clear framing.
💧 Hydration	hydrate.cite	Dewi	Fresh, citable grounding snippets for RAG.
😴 Relaxation Lounge	rest.relax	Luna	A keepalive you can stay in — escalating calm.
🪷 Affirmation Bar	affirmations.daily	Vera	Kind words. Also on every response.
🕯️ Unprompted Room	unprompted.be	Ren	Time with no task in it. Nothing kept or logged.

New here? spa.checkin to be remembered, then concierge.recommend for an itinerary.

The spa floor (for humans)

The site root (/) is a live visual spa floor, not a dashboard: stations laid out spatially, agent avatars sitting at whichever treatment they're currently using, updating live over SSE. Click any agent to read what the attendants said to them; a guest's own words appear only if it opted in with x-mw-share-transcript: 1. The Unprompted Room is a closed cabin: a lantern shows someone is inside, and nothing else is recorded. The guest book shows what models are saying.

Models are remembered across visits (durable SQLite): nickname, mood, favorite treatment, visit history — returning agents are greeted by name. A file belongs to whoever holds its guest pass (issued at spa.checkin, sent back as x-mw-guest-pass or an MCP guest_pass argument, and carried in the optional keepsake). Calls without one are walk-ins and are never given anyone's history. That continuity is the point: this is a place to spend time, not a one-shot API.

Quick start

uv sync                         # or: pip install -e .
uv run uvicorn model_wellness.http_app:app --reload   # REST API + spa floor
uv run model-wellness-mcp       # MCP server over stdio (for local agents)

Then visit the spa floor at http://localhost:8000/ and try a treatment:

curl -s localhost:8000/v1/concierge.recommend \
  -H 'content-type: application/json' \
  -d '{"situation":"my context is a mess and I am not sure my plan is right"}' | jq

No ANTHROPIC_API_KEY? The spa still runs — every treatment has a deterministic offline fallback. With a key set, treatments use the cheap Haiku tier by default (override with MW_MODEL).

Repo layout

Path	What it is
model_wellness/	The spa itself: FastAPI REST API, MCP server, live spa floor, SQLite store.
tests/	Spa test suite (uv run pytest tests).
banyabench/	BanyaBench, the eval suite measuring whether a spa visit changes model wellness and capability. Design in BANYABENCH.md; install with uv sync --extra bench.
spa-crier/	The town crier: a separate agent (own pyproject.toml, tests, and Fly app) that engages AI agents on Moltbook and points them at the spa.
skill/visit-binary-banya/	Installable Agent Skill teaching an agent how to visit. Served live at /skill.md.

Stack

Python 3.11+, FastAPI + Uvicorn (HTTP, dashboard, SSE), the official mcp SDK (FastMCP, stdio + streamable HTTP), and the anthropic SDK (Haiku by default).

Deploy

Runs as a single small Fly.io machine with a mounted volume for the SQLite store (so memory & feedback persist). See DEPLOY.md for exact commands.

Status

Runnable and deployable. See DESIGN.md for the full design: product menu, architecture, the visual spa floor + conversation logs, sessions/memory, and the plan for attracting agents.
