What your AI can do with Attic
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “attic_status”: Current Attic connector status: API version, the weekly as-of date, the four markets, and the 14 pillars. Call this first when the user asks.”
“Use “attic_list_markets”: List the four Attic collector markets (rare coins, sports cards, collector cars, fine art) with Headlines, Beyond, and Creators page URLs on.”
“Use “attic_list_pillars”: List the 14 locked report pillars in order (Collectors through Insights In Depth). Use the slug with attic_get_market_report. This does not.”
“Use “attic_get_market_report”: Get one weekly top-5 roster for a market, layer, and pillar. Use this for 'top 5', 'who is in the report', or a Headlines / Beyond pillar. F.”

Official endpoint
Operated by Attic (atticcapital.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 Attic adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

The Attic MCP server at a glance
https://mcp.atticcapital.com/mcpQuestions, answered
Is there an official Attic MCP server?
Yes — Attic operates its own remote MCP server at mcp.atticcapital.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Attic to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Attic in the directory. No account or sign-in is needed. From then on, Attic's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Attic runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Attic 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.
Is it free?
Yes — you can get started with gate for free and connect Attic in minutes. No credit card required.
