## MCP servers and AI connectors

None recorded on public pages we checked.

## What the docs don't say

- The page says the APIs currently include submissions history by filer and XBRL data from financial statements; the page does not mention Form ADV adviser data.
- data.sec.gov does not support CORS, so browser JavaScript cannot call it directly.
- The EDGAR APIs page does not state the User-Agent requirement itself; it is on the Accessing EDGAR Data page.
