About
Quartr holds first-party investor relations material from more than 16,000 public companies across 65 markets: live and recorded earnings calls, transcripts with speakers identified, slide decks, filings and reports, and a summary of each event. It is the record of what management actually said, to quote rather than paraphrase, and it reaches markets outside the US that most transcript sources skip.
MCP access comes with Quartr Pro and needs it; student plans are not eligible. Click Add and sign in when the window opens. There is no API key to find.

Frequently asked questions
- What is a Connector?
- A Connector is a remote MCP server that a third party runs and Marvin Labs knows how to reach. Marvin Labs supplies the endpoint and the setup; you bring your own Quartr account. Once added, AI Analyst Chat and Deep Research Agents call its tools when a question needs them, and the answer shows which tool was called and what it returned.
- Does the Quartr Connector require authentication?
- Yes. Adding Quartr opens its sign-in window, where you approve access with your own Quartr account. Marvin Labs never sees your password; Quartr issues a token you can revoke on its side at any time.
- Does Quartr change how financial data is sourced?
- No. When a question can be answered from the filings, earnings calls, and press releases Marvin Labs ingests through Automated Data Import, it answers from those. Quartr is used only when a question needs data those documents do not carry, and the answer attributes that output to it.
- Where is Quartr available?
- In both AI Analyst Chat and Deep Research Agents. Its tools stay out of the model's context until a request needs one, so an unused Connector takes up no context window.
