- Transport: Streamable HTTP
- Category: Search & AI memory
- You need to fill in: Authorization
Install
Pick the AI app you use, then copy the settings.
Before you install
- Basic checks: 1 of 1 passed
- Runs on the maker’s server: what you ask it goes through their server.
- You fill in yourself:
Authorization
Values marked secret are keys to your account. Never share them or paste them into a chat.

Which app do you use?
Pick your app above. We remember it, so next time the button says “Install in …”.
This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.
Run this in your terminal
claude mcp add --transport http vramglass https://mcp.vramglass.com/mcp --header 'Authorization: Bearer {api_key}'Fill in the empty values before running it.
Or copy the settings yourself
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json
{
"mcpServers": {
"vramglass": {
"url": "https://mcp.vramglass.com/mcp",
"headers": {
"Authorization": "Bearer {api_key}"
}
}
}
}Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Common questions
Is VRAMGlass safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: Authorization
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 16 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

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.
https://mcp.vramglass.com/mcpRemote server, Streamable HTTP, read-only. Free; a VRAMGlass account is required.
Developer docs · 简体中文文档 · 日本語ドキュメント · MCP page · Methodology
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)
- Sign up or log in at vramglass.com/login. It's free; an email address is enough.
- 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.
- Send this to your AI, with
YOUR_KEYreplaced 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.
| Tool | What it returns |
|---|---|
get_prices | Current prices for GPUs or memory on eBay, Xianyu and Amazon Japan: median, price range and listing count |
get_price_history | Daily price history, from the last 7 days up to a year |
get_price_index | The GPU price index and its price tiers |
search_hardware | Find GPUs and memory by name |
search_models | Find LLMs and their versions by name |
models_for_gpu | Which models a GPU can run, and how long a context fits |
gpus_for_model | How much VRAM a model needs, which cards can run it and roughly how fast |
recommend_build | PC builds for a model (GPU, CPU, motherboard, RAM, PSU) with an optional budget, prices and buy links; GPU options instead when the model fits entirely in VRAM |
get_ebay_deals | The eBay deals shown on GPU and memory pages: the same rule-filtered listings, up to six |
get_rent_prices | Hourly rental prices on RunPod, Vast.ai and Compshare |
All tools are read-only. Results include a page_url and a cite line for attribution.
Keys, access and usage
- A key or an authorized app can only read public price and spec data. It can't see your email, price alerts or watchlist, and it can't change anything in your account.
- Use one key per tool so you can turn each one off separately. Each account can have up to 5 keys, each valid for up to one year.
- Revoke a key or disconnect an app under MCP connections; it stops working within 30 seconds.
- It's free. If you call it too often you'll be rate-limited briefly, then it recovers on its own. For heavy use, email hello@vramglass.com.
Data and citation
- Prices are the median asking price of listings currently for sale, not sold prices. eBay (US), Xianyu (China) and Amazon.co.jp (Japan) are counted separately.
- Prices update every 6 hours. A round with too few valid listings doesn't publish a price.
- When you cite the data, credit "VRAMGlass", link back to the relevant page and state the marketplace and date of each price.
- VRAM and speed figures are planning estimates, not benchmarks. See the methodology.
- Buy and rental links carry VRAMGlass referral parameters. The price you pay stays the same.
