You can use the Apixies tools in Claude without installing anything. Add one URL as a connector, sign in, and Claude can check certificates, look up DNS, parse sitemaps and convert data for you. It works on the web, on desktop and on your phone.
The URL is:
https://apixies.io/mcp
Add it to Claude
- In Claude, open Settings, then Connectors.
- Pick Add custom connector.
- Name it
Apixiesand pastehttps://apixies.io/mcpas the URL. - Click Connect. A browser tab opens on apixies.io.
- Log in (or sign up, it's free), then click allow.
That's it. There's no API key to copy. Claude gets its own token for your account, and you can take it away again on your API keys page.
Now ask for something:
Check the SSL certificate for stripe.com and tell me when it expires.
Claude calls check_ssl and answers from the real response. The first time it uses a tool it asks for permission. All the tools are marked read-only, so you can safely pick "always allow".
What you get
47 tools, the same ones as the API. A few that work well in a chat:
check_ssl,check_headers,validate_email_authfor a quick security look at a domaindns_lookupanddns_propagationwhen a DNS change isn't showing upwhois_lookupfor expiry dates and registrarsparse_sitemap,check_link,trace_redirectsfor SEO checksjson_to_csv,yaml_to_json,json_diff,test_regexfor data chorestake_screenshot, which hands Claude the image so it can look at the page
A prompt that uses several at once:
Do a health check on example.com: SSL, security headers, SPF and DMARC, and whether the sitemap loads. Give me a short list of what to fix.
What it costs
Nothing. Every tool call counts as one request against your account's daily limit of 75, the same as a call with an API key. If you run out, the tool answers with DAILY_QUOTA_EXCEEDED and Claude will tell you. It resets at midnight UTC.
Other clients
Anything that speaks MCP over HTTP with OAuth can use the same URL.
Claude Code
claude mcp add --transport http apixies https://apixies.io/mcp
Then run /mcp inside Claude Code and pick Apixies to sign in.
Cursor, VS Code and others take a config like this:
{
"mcpServers": {
"apixies": {
"url": "https://apixies.io/mcp"
}
}
}
Hosted or local?
There are two ways to run the Apixies tools, and they don't get in each other's way.
The hosted connector (this page) needs no install and no key, and it's the only one that works in Claude on the web and on mobile. It leaves out three tools. html_to_pdf and markdown_to_pdf can't return a file through a hosted connector, and my_ip would tell you our server's view of Claude's address, which isn't yours.
The npm server runs on your machine with an API key. It has all 50 tools. Use it if you live in Claude Desktop, Claude Code or Cursor and want everything. On Claude Desktop you can install it with one click from apixies.mcpb.
What Apixies sees
Only what a tool needs. When Claude calls check_ssl for a domain, we get the domain. We don't get your conversation, your files or anything else from Claude. Calls are logged with your account for up to 90 days so quotas work and problems can be traced. Text, HTML and email fields are redacted in those logs. The details are in the privacy policy.
When something goes wrong
The login tab doesn't come back to Claude. Finish on apixies.io first. After you click allow, the tab sends you back on its own. If you closed it, click Connect again.
"Couldn't reach the MCP server." Check the URL. It's https://apixies.io/mcp, with no trailing slash and no /api.
A tool says DAILY_QUOTA_EXCEEDED. You've used your 75 requests for today.
You want to disconnect. Open API keys on apixies.io and click disconnect next to the app. Its access ends right away. Then remove the connector in Claude's settings too, so it stops asking.
