PIXIE MCP Server
Manages Obsidian vault files, enabling preview of inbox-to-project moves with rollback receipts while preserving original filenames and attachments.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@PIXIE MCP Serverevaluate my current portfolio allocation"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
PIXIE Holdings
Loptr Lab mission and participation
Loptr Lab is a pre-seed, people-over-profit, accessibility-first venture working toward a self-sustaining model within a capitalist economy. Money sustains the work; meaningful change for people is its purpose. We accept funding only on terms that keep people and accessibility first. Our long-term vision includes universal basic income. We aim to bring change to life and leave a transparent record of what we tried, what worked, and what failed so others can carry it forward. This mission governs our projects, funding decisions, and partnerships; it is not a temporary marketing position.
Current open review and contribution opportunities are voluntary and unpaid. Before work begins, agree in writing on scope, time, what will be public, credit preferences, and an exit path. You can stop at any point. Participation does not promise employment, ownership, revenue share, academic credit, or future pay. Any paid commission or other formal arrangement requires a separate signed agreement before work begins. External assistance or benefits belong to the participant and are not compensation from Loptr Lab.
Financial support is optional and sustains infrastructure, maintenance, accessibility work, and documented development. Paying does not buy contributor status, canon authority, approvals, ownership, or employment. Participation and accessibility are not sponsorship rewards. Project-specific licenses and existing signed agreements continue to apply.
Full mission and participation terms.
Open-source prototype created for the Build, Ship, Shape: Amazon Developer Hackathon.
PIXIE Holdings is an accessible portfolio-economics game. The player stewards three fictionalized Loptr Lab holdings while balancing cash, human capacity, accessibility, rights, trust, and system pressure.
The project demonstrates a deliberately different kind of embodied assistant:
Alexa+ is the voice through a self-hosted MCP endpoint.
PIXIE is the consent and consequence steward.
AT Protocol is the portable public evidence layer.
Narrative Provenance for Obsidian remains the private creator-controlled memory.

Contributor launchpad
Run it. Test it. Tell us what breaks.
Start with CONTRIBUTING.md. Good first contributions include accessibility testing, MCP/Alexa+ interoperability, documentation, provenance, UX, tests, and ecosystem mapping.
The Ecosystem Handoff explains how this hackathon prototype fits into the wider Loptr Lab / PIXIE architecture without treating future Gamer OS capabilities as already shipped.
Obsidian vault contract
The prototype includes an additive, Obsidian-compatible project structure in
obsidian-vault/. PIXIE may propose an inbox-to-project
move, but it must show the source path, destination path, reason, and rollback
receipt before changing anything. Original filenames and attachments are preserved.
Run
Requires Node.js 22 or later.
npm install
npm startOpen http://localhost:3000. The MCP endpoint is POST /mcp; health is GET /health.
npm testNew Economy market reference layer
The Holdings market surface uses server-side provider credentials for external reference data. The production GitHub Pages site receives a generated static snapshot at public/market-data.json; the Node server retains /api/market for local/server deployments:
Financial Modeling Prep (
FMP_API_KEY) for equities, ETFs, and crypto quotes.Federal Reserve Bank of St. Louis FRED (
FRED_API_KEY) for macroeconomic observations such as the 10-year Treasury yield (DGS10) and volatility index (VIXCLS).
Set these variables in the deployment environment; never commit provider keys or put them in browser code. The Pages workflow reads FMP_API_KEY and FRED_API_KEY from GitHub Actions secrets, generates the static snapshot, and deploys only the resulting public data. It refreshes on main pushes, manual runs, and a 15-minute schedule. Provider freshness depends on the subscribed data plan; FRED is an observation series rather than a continuous ticker.
All market records are normalized with referenceOnly: true. External market data cannot mutate PXCOIN, allocations, trust, rights, capacity, governance, or other synthetic game state.
Alexa+ MCP
The server implements the MCP 2025-11-25 JSON-RPC surface needed for the prototype:
initializetools/listtools/call
Tools:
list_holdingsevaluate_allocationpreview_file_actionprepare_media_packageprepare_public_receipt
The receipt tool creates a preview only. It does not publish, spend, order, diagnose, or transmit private information.
Training pathway
The Loptr Lab training pathway routes visitors by creative interest and present capacity. Job-loss context remains device-local and is never included in the public PDS-record preview.
Rights boundary
The playable prototype uses original Loptr Lab names and mechanics. Umbrella Corporation, Wayne Enterprises, V.I.K.I., the Red Queen, Pennywise, IT, Resident Evil, artists, platforms, and publications may be discussed as commentary or inspiration but are not included as characters, branding, endorsements, or licensed properties.
The economic figures are synthetic scenario data, not valuations, investment advice, financial statements, or offers of securities.
