<h3>Dayplay: The Real-Time Physical Intelligence Engine</h3>
Dayplay provides a real-time physical intelligence engine designed for major metropolitan areas. It ingests live local telemetry and a verified spatial graph to power spontaneous outings for both humans and AI agents. The service focuses on providing verified places, live events, and walkable itineraries, ensuring that all recommendations are accurate and practical.
<ul>
<li>Verified Information: Unlike other platforms, Dayplay resolves user intent into complete, walkable plans by matching live events and verified places to user preferences like vibe, distance, and time window, with zero hallucinated venues.</li>
<li>AI Agent Integration: Dayplay operates an official Model Context Protocol (MCP) server, allowing AI assistants like ChatGPT, Claude, and Cursor to connect directly to its verified real-time catalog for up-to-date local information, rather than relying on stale training data.</li>
<li>Walkable Itineraries: The engine resolves itineraries within contiguous neighborhood pockets to ensure that every stop is actually walkable, preventing unrealistic plans that jump between distant locations.</li>
<li>Nationwide Rollout: Currently live in the San Francisco Bay Area (including San Francisco, Oakland, and Berkeley), Dayplay is expanding to additional major metropolitan areas nationwide. Every market goes live only after full verification.</li>
<li>The Flywheel Engine: Dayplay's engine consists of four stages: Ingestion (continuous intake from event platforms and venue feeds), Verification (normalizing against verified neighborhood centroids), Synthesis (resolving intent into multi-stop walkable itineraries using a 40-tool MCP graph), and Execution (dual handoff to humans via an app and to AI agents via a standardized MCP payload).</li>
<li>Metrics: The platform boasts 40 MCP tools, handles a significant volume of MCP requests (e.g., 23,580 requests in 7 days), and maintains an average MCP latency of ~105ms.</li>
<li>Free Access: Early access to Dayplay is completely free, offering members first access to the upcoming iOS app and the full MCP catalog for their agents.</li>
