MCP Inspector
Connect to a remote MCP server over Streamable HTTP or SSE, list tools, and call them. No signup and no proxy.
Browser-only. No account and no proxy: the request goes from your browser to the server you name. Auth headers stay in this tab’s memory. They are not put in the link, history, or this page’s result text. A shared link does not connect or call anything.
Usernames, passwords, and sensitive query parameters are stripped before anything is stored in the address bar.
Cleared when you disconnect or leave this page. Not included in the share link.
Nothing has been contacted.
Tools
If the browser blocks the server, paste a tools/list JSON response. That list is local. Call stays off.
