Official endpoint
Operated by Sphere Marketplace (starsphera.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Sphere Marketplace adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

The Sphere Marketplace MCP server at a glance
https://starsphera.com/mcp/sseQuestions, answered
Is there an official Sphere Marketplace MCP server?
Yes — Sphere Marketplace operates its own remote MCP server at starsphera.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.

Add gate's gateway URL to your AI client once, then pick Sphere Marketplace in the directory. No account or sign-in is needed. From then on, Sphere Marketplace's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Sphere Marketplace runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Sphere Marketplace MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
