Singapore LTA DataMall MCP Server
https://mcp.techmavie.digital/ltadatamallsg/mcp ↗
Description
Access real-time public transit information including bus arrivals, train service alerts, and station crowding levels in Singapore. Check live parking availability and monitor expressway travel times or traffic incidents for smoother commutes. Plan journeys more effectively using forecasted crowd levels and up-to-the-minute road updates. This MCP is an enhanced fork of arjunkmrm/lta-mcp, rebuilt for self-hosted VPS deployment with zero-friction onboarding.
What our measurements say
Singapore LTA DataMall MCP Server is a remote MCP server published at mcp.techmavie.digital. It has been probed 7 times since 9/10/2026. It answered in 7 of them (100.0%), a near-uninterrupted record. Median response time is 142 ms, placing it among the faster endpoints. It offers a narrow, focused set of 8 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names clearly indicate their primary function (e.g., 'bus_arrival', 'carpark_availability').
- Descriptions include update intervals (e.g., 'every 5 minutes') for temporal context.
Weaknesses
- Similar tools like 'station_crowding' and 'station_crowd_forecast' risk confusion due to overlapping domains.
- Parameter requirements (required/optional) are not explicitly defined in descriptions.
- No mention of error handling or constraints (e.g., invalid bus stop codes).
station_crowding— Overlaps with 'station_crowd_forecast' in purpose but differs in temporal scope.bus_arrival— Parameter 'service number' is marked as optional but lacks explicit clarification in description.travel_times— No explicit mention of expressway segment identifiers in description.
Verdict
Event narrative
Risk: medium
- 2026-09-10T21:16:35.016Z — era changed from auth-gated to legacy · transition to legacy mode with full compliance
- 2026-09-11T05:44:28.819Z — compliance score set to 100 · stability period with no changes
Advice
Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- tools/list schema valid
- inputSchema is valid JSON Schema
- Smoke test not run this round
- Cold-start: cold 32ms → warm 32ms (penalty 0ms)
