Use Passage Data from your AI assistant

Add one address to the assistant you already use. Ask it about a discharge limit, a permit, a DMR, a lab report or a species at risk, and it answers with the regulation, edition and page each number came from. Free.

1 · Add the address

The address: https://passage-data.com/mcp

In a chat app

Claude: Customize → Connectors → + Add → Add custom connector; paste the address; choose No sign in. Free plan: one custom connector.
ChatGPT (paid plans, on the web): Settings → Apps → Advanced settings → turn on Developer mode; Create app, paste the address, no authentication.
Microsoft 365 Copilot: your IT adds the address in Copilot Studio (Tools → Add a tool → New tool → Model Context Protocol; authentication None) and publishes the agent to Teams and Copilot.

2 · Ask in your own words

Limits and rules

“What is the monthly average copper limit for a mine's effluent in Québec?”
“Is 0.4 mg/L of copper over it?”
“An AI told me the MDMER copper limit is 0.3 mg/L. Is that right?”

Lab reports

“Read this lab certificate and tell me which results are over Ontario's limits.”

read_certificate

US discharge permits and DMRs

“What are the limits on permit TX0141429, and when is its renewal due?”
“Here are September's results for outfall 001. Will EPA flag my DMR?”

Or on the web, no assistant: check a discharge report.

Species at risk

“Is the little brown myotis protected in Ontario, and under which act?”
“Which species on this list are at risk in New Brunswick?”

Species records for GBIF

“Turn this spreadsheet of bird sightings into a Darwin Core archive for GBIF.”

Public documents

“On which page of this environmental assessment is 4,000 mg/L chloride printed?”

Your project's documents

Needs a free account; your assistant asks you to sign in the first time.

“Add this permit to my project, then tell me what it says about chloride.”

Where the answers come from

Every number comes with the document, edition, page and quoted text it was read from, so you can check it before you rely on it. When we hold nothing, the answer says what was searched; it never says the law has no limit.
