Fallax MCP server

Fallax is the official remote MCP server from fallax.io. It answers at https://app.fallax.io/mcp over streamable HTTP and asks you to sign in with your fallax.io 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 Fallax 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 fallax.io account, and the tools appear once you have approved it.

Does Fallax 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: io.fallax. Endpoint host: app.fallax.io. ARD identifier: urn:air:io.fallax:mcp:fallax. 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.
