LaunchFlag MCP server

LaunchFlag is the official remote MCP server from launchflag.dev. It answers at https://launchflag.dev/api/mcp over streamable HTTP and asks you to sign in with your launchflag.dev account before it lists its tools, so your client opens a login the first time it connects. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, got the sign-in challenge, so it is up.

Description as the publisher wrote it.

What LaunchFlag needs before it works

A sign-in. The server refused to list its tools to an anonymous client and answered with an authentication challenge, which is how an MCP server protected by OAuth behaves. Add it with one of the setups below; the first connection opens a login for your launchflag.dev account, and the tools appear once you have approved it.

Questions about LaunchFlag

Is there an official LaunchFlag MCP server?

Yes. It is published by launchflag.dev and served from launchflag.dev, the vendor's own domain: https://launchflag.dev/api/mcp.

How do I sign in to LaunchFlag?

Add the server with a setup above. The first time your client connects it opens the sign-in page for launchflag.dev; approve it and the tools load.

Is LaunchFlag down?

It answered our last check on 19 October 2026 in 166 ms. Over 6 checks since 10 September 2026 it answered 6.

How do I add LaunchFlag to Cursor?

Does LaunchFlag need an API key?

It needs a sign-in rather than a key you paste: the server answered with an authentication challenge, so your client runs the login when it first connects.

Where this comes from

Publisher: dev.launchflag. Endpoint host: launchflag.dev. ARD identifier: urn:air:dev.launchflag:mcp:launchflag. First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page is inferred from its name. Ranking in Neuronto search is never for sale.
