Server returning HTML 404 pages instead of JSON error responses
I deployed a MCL server for SEC-API.io’s APIs. i’m getting the following errors in claude desktop when i use it though — Error from SEC API: 404 Not Found. <!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Error</title>
</head>
<body>
<pre>Cannot GET /full-text-search</pre>
<pre>Cannot GET /filing/000110465925051582</pre>
</body>
</html>
What's Broken:
API endpoints don't exist on the server
Server returning HTML 404 pages instead of JSON error responses
Multiple different endpoints all failing with same pattern
