What data it sees

Do you need an account

No: the server works without sign-in

The Montreal Construction Oracle is a specialized Model Context Protocol (MCP) server that provides structured, real-time access to building permit data from the City of Montreal.

Instead of manually digging through messy government CSVs, this server allows AI agents (like Claude, ChatGPT, or custom enterprise bots) to instantly query high-value construction leads, renovation trends, and urban development data.

How to connect

How to connect MontrealPermitOracle2 to Claude

The server address to paste into Claude settings:

https://montrealpermitoracle2--maximeproulx4.run.tools

  1. Open Claude (claude.ai or the desktop app).
  2. Go to Settings → Connectors.
  3. Click Add custom connector.
  4. Paste the server address copied below into Remote MCP server URL and click Add.
  5. In a chat, click + → Connectors and switch the new connector on.

Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

Authorization

After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

How to connect MontrealPermitOracle2 to ChatGPT

The server address to paste into ChatGPT settings:

https://montrealpermitoracle2--maximeproulx4.run.tools

  1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
  2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
  3. Open Settings → Connectors and click Create.
  4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
  5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
  6. In a new chat open + → Apps/Connectors and enable the connector.

OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

Authorization

On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

https://montrealpermitoracle2--maximeproulx4.run.tools

Fastest: click Open in Cursor below and confirm the prompt.

Manually:

  1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
  2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
  3. Save the file. The server appears in the MCP list; authorize it there if asked.

Authorization

If the service needs sign-in, an authorize button appears next to the server in the MCP list.

Server tool list (4)

Raw names from tools/list. Only developers need these.

get_recent_permitsReturn building permits issued in the given Montreal borough within the last N days. Borough matching is case-insensitive and supports partial names (e.g. 'plateau' matches 'Le Plateau-Mont-Royal').
get_high_value_permitsReturn large-scale building permits filtered by estimated work cost. NOTE: the Montreal Open Data CSV does not currently publish the 'cout_travaux_estimes' column. This tool uses 'nb_logements' (housing unit count) as a scale proxy: min_cost is divided by 100 000 to derive the minimum unit threshold. Results are sorted largest-first. The tool will automatically switch to real cost data if the column appears in a future dataset update.
list_boroughsList all 19 distinct borough (arrondissement) names found in the permit dataset. Use the returned names as input to get_recent_permits().
reload_dataClear the session cache and re-download the permit CSV from the Montreal Open Data portal. Useful if the dataset has been updated since the server started.
