Accessibility Mobility Context Router

🎯 The Idea

Problem: People with disabilities face significant challenges when planning trips. Standard navigation apps don't account for:

• Elevator/escalator outages in transit systems that block accessible routes
• Venue accessibility information (wheelchair access, audio guides, tactile paths, etc.)
• Weather conditions that affect mobility (rain, snow, extreme temperatures)
• The need for extra buffer time for accessible travel
• Integration with calendar events to proactively plan trips
• Real-time accessibility barriers that can disrupt travel plans

Solution: An MCP (Model Context Protocol) server that fuses multiple data sources to provide people with disabilities a comprehensive, accessibility-first context package for trip planning. Instead of just "how to get there," it answers "how to get there safely and accessibly."

Key Innovation: By combining calendar intent (next meeting), real-time transit accessibility data (elevator/escalator outages), venue accessibility tags (OpenStreetMap), weather risks, and route planning, we create a context package that gives AI assistants everything they need to provide informed, accessibility-aware guidance.

Impact: This transforms trip planning from a multi-step, error-prone process into a single question: "How do I get to my next meeting?" The system automatically considers accessibility barriers, suggests alternatives, and provides evidence-linked recommendations.

🌍 Who This Helps

This MCP server benefits people across the accessibility spectrum:

• Wheelchair Users: Real-time elevator/escalator outage alerts, venue wheelchair accessibility verification, accessible route planning with buffer time
• Blind and Visually Impaired: Detailed route descriptions, alternative route options when primary paths are blocked, weather conditions that affect navigation
• Mobility Impairments: Accessible transit options, venue accessibility information, weather-aware planning for conditions that affect mobility
• People with Chronic Conditions: Buffer time recommendations, weather risk assessment, alternative routes when primary options are unavailable
• Elderly Travelers: Comprehensive accessibility information, clear route alternatives, proactive barrier detection

The system's context package provides structured, evidence-backed information that AI assistants can adapt to each user's specific needs, whether they require wheelchair-accessible routes, detailed verbal descriptions, or weather-sensitive planning.

🚀 What This MCP Server Does

This MCP server is a specialized tool for AI assistants (like Claude) that helps people with disabilities plan accessible trips. When you ask "How do I get to my next meeting?", the server:

1. Fetches your next calendar event (title, time, location) from Google Calendar via ICS feed
2. Finds multiple route candidates (transit, walking, driving) using Google Maps Directions API
3. Checks for elevator/escalator outages on NYC MTA transit routes that could block accessible paths
4. Verifies venue accessibility (wheelchair access, accessibility features) using OpenStreetMap Overpass API
5. Assesses weather risks around travel time using OpenWeather API
6. Calculates optimal departure time with configurable buffer minutes
7. Fuses everything into a compact context package with citations and evidence

The result is a structured JSON package containing:

• Highlights: 5 key bullets summarizing route, accessibility alerts, venue access, weather, and timing
• Alternatives: Backup route options if the primary route has issues
• Citations: Links to source data (maps, transit status, weather forecasts)
• Metadata: Event details, origin/destination, sources used

This context package enables AI assistants to provide natural, evidence-backed answers like:

"Take the Q train from Times Square to 86th St (20 min). Leave by 3:40 PM to arrive by 4:00 PM with a 20-minute buffer. Note: There's an elevator outage at 57th St station—consider the alternative route via 96th St. The Met is wheelchair accessible. Light rain expected—bring an umbrella."

Data Flow

1. Input: User asks "How do I get to my next meeting?" via MCP tool
2. Calendar: Fetch next event (title, time, location) from ICS feed
3. Geocoding: Resolve location text to lat/lng coordinates
4. Parallel Data Fetching:
   • Directions API → Route candidates
   • MTA API → Elevator/escalator outages
   • OSM Overpass → Venue wheelchair tag
   • OpenWeather → Weather forecast
5. Fusion: Score routes, identify best option, generate context bullets
6. Output: Structured context package with highlights, alternatives, citations

Key Design Decisions

• Mock Mode: Graceful degradation when API keys are missing (deterministic demo data)
• Timeout Protection: All HTTP requests have configurable timeouts (default 3s)
• Citation Links: Every piece of information includes source links for verification
• Buffer Time: Configurable extra time for accessible travel (default 20 minutes)
• Error Handling: Server continues processing even if individual data sources fail

🔮 Future Improvements

This MVP provides a solid foundation for accessibility-aware trip planning. Potential future enhancements include:

• Expanded Transit Coverage: Support for additional transit systems beyond NYC MTA (e.g., other major cities' transit APIs)
• Enhanced Accessibility Data: Integration with crowdsourced accessibility platforms and venue-specific accessibility databases
• Personalization: User preference profiles for accessibility needs, preferred transit modes, and buffer time preferences
• Advanced Route Intelligence: Machine learning-based route scoring and predictive outage detection using historical patterns
• Multi-Calendar Support: Integration with additional calendar providers (Outlook, Apple Calendar, etc.)

These improvements would enhance the MCP server's capabilities while building on the current accessibility-first foundation.
