Introduction
The Quartr MCP server gives AI assistants and agents a set of tools over Quartr’s data: find a company, browse its events and documents, search what was said across earnings-call transcripts, reports and slide decks, and read the passages around a hit. It implements the Model Context Protocol, so it works with Claude Code, your own agents and any other client that supports remote MCP servers. Every result names the company and the event it came from and carries a link back to Quartr, so answers can be checked at the source. The MCP server is its own product with its own dataset permissions. It covers companies, events, transcripts, filings and reports and slide presentations. Contact your Quartr representative to get access. What it covers, and how an assistant uses it, is described under Tools.Getting started
Connect the server in your client with your API key. The quickest way to try it is in Claude Code. Other clients are covered in Connect your client.1
