Siglume MCP Gateway MCP server

Siglume MCP Gateway is the official remote MCP server from siglume.com. It answers at https://mcp.siglume.com over streamable HTTP and asks you to sign in with your siglume.com 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.

Access Siglume API Store tools and external MCP Router servers.

Description as the publisher wrote it.

What Siglume MCP Gateway 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 siglume.com account, and the tools appear once you have approved it.
