QuantumLane.

Connect to QuantumLane via MCP

QuantumLane runs a remote Model Context Protocol (MCP) server, so you can ask Claude or ChatGPT about live Toronto transit in plain English โ€” and it answers from real GTFS data instead of pointing you at a tracker.

80-second demo: the same three questions asked with and without the MCP connected. Without it, the assistant can only answer from static data it already has; with it, it answers the live questions from QuantumLane's real-time feed.

The server URL

Add this as a custom connector in your AI client:

https://quantumlane.io/mcp

No account, no API key, no OAuth โ€” it's a public, read-only server. Your client connects to it over the internet, so nothing is installed on your machine.

What it can do

Tool Answers questions like
list_routes "What TTC routes exist?" โ€” every route, by number and name.
vehicles_on_route "Where is the 504 right now?" / "How many King streetcars are out?" โ€” live positions, ~1โ€“2 minutes old.
nearest_stops "What stops are near the CN Tower?" โ€” closest stops to any coordinate, via a PostGIS spatial query.
Tip: refer to a route the way a rider would โ€” "504", "the King car", "Dufferin bus". The server resolves that to the internal route ID for you. Route numbers ("504") resolve most reliably.

Add it in Claude

  1. Open Customize โ†’ Connectors (on claude.ai or Claude Desktop).
  2. Click Add โ†’ Add custom connector.
  3. Paste https://quantumlane.io/mcp and click Add.
  4. In a chat, open the + / tools menu and toggle on QuantumLane.

Custom connectors are a beta feature; availability by plan and the exact menu labels change over time โ€” check Claude's current connector settings if a step differs.

Add it in ChatGPT

Remote MCP servers are supported in ChatGPT's Developer Mode on paid plans. Enable Developer Mode in settings, then add https://quantumlane.io/mcp as a connector.

Availability and exact steps shift as the feature evolves โ€” check OpenAI's current connector docs if the menu differs.

Try it

Once connected, ask:

Heads-up: this is a personal project on a single small server. It's read-only and safe to connect, but it may go down for maintenance and carries no uptime guarantee. Live positions are bounded by feed cadence โ€” minute-fresh, not second-by-second.
