Market data for Claude: add TradingData as a custom connector

Claude's custom connectors speak MCP over HTTP with OAuth, which is exactly what TradingData serves. Add the URL once; Claude registers itself, sends you here to approve, and from then on sees all 30 tools.

Steps

  1. 1Open Settings, then Connectors, and choose Add custom connector.
  2. 2Name it TradingData and paste the MCP server URL below. Leave the OAuth client fields empty; Claude registers itself automatically.
  3. 3Click Connect. You land on tradingdata.io to sign in and approve access, then you are sent back.
  4. 4In a chat, open the tools menu and enable TradingData. Ask about any market, company or filing.
  • Custom connectors are available on Claude's paid plans and for Team and Enterprise workspaces where an admin allows them.
  • Claude caches the tool list when it connects; if tools are added later, remove and re-add the connector to see them.
