Beesknees MCP

The Bee's Knees

A race to the queen, monetized with Tollbooth DPYC™ Bitcoin Lightning micropayments — and run for the benefit of pollinators.

Buy a drone a seat. Fly it to a flower, carry the pollen home through the hive wall, then tunnel inward. The first bee to reach a queen takes the round. Most of what the round collects goes to pollinator welfare; the winner and the operator each take a small share.

The board

A hive is round because the field has to narrow. Ring 0 is the queen's chamber and ring 14 is the hive wall. Cells scale with circumference, so the wall holds 29 and the last ring before the chamber holds six. Everyone starts spread out and converges into a scrum — 226 cells of comb in all.

Outside the wall the meadow is a square lattice, sixteen cells to a side less the squares the hive covers, and the wall's doors are the only way between the two. A bee crosses the meadow toward a hive it can see from anywhere; inside, the rings funnel every bee toward one cell.

Movement is inward, outward, or sideways along a ring. Sideways is what makes it a maze rather than a set of lanes: it is how you slide onto somebody else's open shaft, or step out from under a collapse. A bee may not move inward twice in a row — it steps sideways between — so a straight radial shaft does not pay, and a small share of the comb is impassable.

The one real choice

**Cut your own shaft — slow, and open to everyone the moment it exists.

Or ride one somebody else paid for — fast, and they can bring it down on you.**

Three motions carry it. fly moves through open ground. dig cuts fresh comb and costs several cooldowns rather than one. seal buries an open cell so the bees behind must cut it again.

A bee acts once per cooldown, measured on the clock, so no amount of spending buys a faster bee. What spending buys is interference.

Why five hives and not one

Five hives of twelve, and a match starts the moment any hive holds eight. Seats go into the emptiest hive, so the five fill evenly.

That is a measured decision, not a taste one. Racing fifty near-identical bees to a single queen is close to a lottery: first-past-the-post among fifty is an extreme-value draw, and those are settled by variance rather than by skill. The batch runner in sim/ puts a good strategy at 1.4x uniform with fifty bees in one hive and 2.1x with twelve. Winning your own hive is skill-weighted; which of the five leaders finishes first is a fair draw, so the signal survives.

Where the money goes

Most of what a round collects goes to pollinator conservation. The default beneficiary is [Pollinator Partnership](https://www.pollinator.org/) — chosen over the honeybee-focused charities on purpose, because managed honeybees are livestock and are not the ones in trouble; native and wild pollinators are, and they are what Pollinator Partnership covers.

How the money leaves

Each settled match records its split: 80% to the charity and 10% each to the winner and the operator, with any rounding going to the charity. The operator pays the shares out over Lightning, and nothing pays on a timer — a payment leaves when the operator asks for it.

• beesknees_pay_charity sends everything owed to the charity in one payment to its Lightning address. The share accrues match by match and settles as a batch, because a single match's share can be smaller than the fee to route it.
• beesknees_pay_out pays one settled match's charity or winner share.
• Every unpaid share is claimed in the database before the sats move, so a retry or a second press cannot pay the same match twice.
• beesknees_treasury shows what the wallet can send against what is owed.
• A player says before the round what happens to a win (beesknees_set_payout). Donating is the default; keeping it needs a Lightning address.

beesknees_settlement_history serves what every settled match paid and to whom, and beesknees_payout_history lists every payment attempted, failures included. Both are free, because a claim about where the money went that costs money to check is not a claim anybody should believe.

The beneficiary is stored, not compiled in, so it can change: the operator names it, its website and its Lightning address with beesknees_set_charity, and beesknees_charity shows it to anyone, free. Every settlement records the beneficiary it actually paid, so history stays true even when the current one changes — a patron who played because of where the money went can always check where it went.

Layout

The rules exist in three copies — this Python, the client's TypeScript, and the renderers — and nothing at runtime reports that they have drifted; the game simply starts rejecting moves a player can see are legal. tests/test_geometry.py and frontend/src/game/rules.test.ts assert the same invariants on purpose, so a drift fails a build instead of a match.

Onboarding roadmap

1. Nostr keypair — generate one (nak key generate); the nsec is the single env var the server needs (TOLLBOOTH_NOSTR_OPERATOR_NSEC).
2. Sponsor Authority — register; it provisions your Neon database.
3. Secure Courier — deliver btcpay_host, btcpay_api_key, btcpay_store_id via beesknees_request_credential_channel. Never as env vars, never in code.
4. Set prices in Pricing Studio — new tools start unpriced, and nobody can call an unpriced tool.
5. Deploy on Horizon — fastmcp.json is already wired.

Get [Pricing Studio](https://github.com/lonniev/tollbooth-pricing-studio) (iOS). It reads and writes the pricing model live in Neon, so prices never live in code — surge, happy-hour, loyalty discounts and free trials are the thing a flat paywall can never give you.

The app

frontend/ carries the Bee's Knees app, deployed to Cloudflare Pages with functions/mcp.js proxying /mcp same-origin. It runs a solo mode against the local engine — the whole match filled with bots but one seat — so the interface can be played before anybody has paid for anything.

The focused hive is drawn in WebGL on top of an SVG first paint. The SVG is what the server-side smoke and prerender checks see, what a browser shows on its first frame, and what the game falls back to if WebGL is lost; the stage takes over once PixiJS has loaded and drawn. Nothing about the game lives in the stage — it renders what both engines already compute.

Develop

uv venv --python python3.12          # coincurve has no 3.14 wheel

uv pip install -e ".[dev]" ruff check . && pytest -v python -m beesknees_mcp.server # runs the validate_operator_tools guard

cd frontend && npm install npm run dev # solo mode on http://localhost:5180 npm test && npm run smoke # invariants, then a real first paint (the SVG one)
