VRAMGlass MCP server

VRAMGlass MCP Server

Live GPU prices, VRAM requirements and local LLM hardware planning for your AI assistant, from VRAMGlass.

Connect it to Grok Bot, Claude, ChatGPT, Claude Code, Codex, Cursor or any MCP client, then ask in plain language. Answers come from the same data as vramglass.com, with links back to the source.

Remote server, Streamable HTTP, read-only. Free; a VRAMGlass account is required.

What you can ask

• "What does an RTX 3090 cost on eBay right now?"
• "How much VRAM does Qwen3.8 27B need at 4-bit with a 32K context?"
• "Which models can a DGX Spark run, and how fast?"
• "Build me a PC for DeepSeek V4 Flash under $5,000."
• "Are used GPU prices going up or down this month?"
• "How much is renting an A100 per hour?"

For example, asked for RTX 3090 prices on October 22, 2026, the server returned a median eBay (US) asking price of $1,799 across 110 listings, ¥8,600 on Xianyu and ¥416,420 on Amazon.co.jp, each with its publish time and a link to the VRAMGlass page.

Connect

With an API key (recommended)

1. Sign up or log in at vramglass.com/login. It's free; an email address is enough.
2. Create a key under Your account → MCP connections. Give it a name, choose how long it stays valid and copy it right away; it is shown only once.
3. Send this to your AI, with YOUR_KEY replaced by your key. Grok Bot, Claude Code, Codex, Manus, WorkBuddy and other assistants that can change their own settings add the server themselves:

Please add a remote MCP server:
   Name: VRAMGlass
   URL: https://mcp.vramglass.com/mcp
   Header: Authorization: Bearer YOUR_KEY
   Once it's added, try it by checking what an RTX 4090 costs right now.

Manual configuration

Any client needs two things: the server URL and the header Authorization: Bearer YOUR_KEY. Choose HTTP (Streamable HTTP) as the transport.

Claude Code:

claude mcp add --transport http vramglass https://mcp.vramglass.com/mcp --header "Authorization: Bearer YOUR_KEY"

Cursor and other clients that use mcp.json:

{
  "mcpServers": {
    "vramglass": {
      "url": "https://mcp.vramglass.com/mcp",
      "headers": { "Authorization": "Bearer YOUR_KEY" }
    }
  }
}

With OAuth (no key)

Connectors in Claude (web and desktop) and ChatGPT can't take a key, so they sign in instead. Any other client that supports MCP OAuth works the same way.

• Claude: Settings → Connectors → Add custom connector, and paste the server URL.
• ChatGPT: Settings → Apps, turn on developer mode, then create an app with the server URL.

Your client opens the VRAMGlass login page. Log in with an email code or Google (an account is created if you don't have one), check the app name and return address on the consent page, and click Allow. The client renews access by itself; after 30 days without use, or 180 days after you authorized it, you sign in again.

Tools

The assistant picks the right tool by itself; you don't need to remember these names.
