Grandet MCP Server: Find the Cheapest Model API in Claude, Cursor and Other Apps
Lets Claude, Cursor and other assistants look up the lowest listed price for any AI model API, and find free credit.
Grandet compares the listed prices of a model across official APIs, inference providers and relay sites, and the assistant can read them through this hosted server. You can also ask what is free and what a relay site's jargon means. It needs no sign-up or API key, and it only reads data. It ranks by listed price alone, so a low price says nothing about quality, and the project says so itself.
Good for
- Developers choosing which API to buy for Claude Code, Codex or Cursor
- Anyone hunting for free model credit without a card
- Teams that want to compare official prices with relay-site prices in one answer

Tools
Finds the cheapest listed price for a model
Compares listed prices for one model across official APIs, inference providers and relay sites. It lists the lowest few with conditions, and you can say what you will use it for or which app will call it.
Try: “Find me the cheapest Claude Sonnet 4.6 API for coding in Claude Code.”
Network ·
grandet_find_cheapest_apiFinds free tiers and free credit
Lists official free tiers, trial credit and relay free groups, with the benefit, requirements, deadline and claim link. It can leave out offers that need a card.
Try: “Is there a free Gemini API I can use without a credit card?”
Network ·
grandet_find_free_creditsLooks up the exact model name
Returns candidate model identifiers when a name could mean several models. It does not rank providers.
Try: “Which exact model IDs match "sonnet 4.6"?”
Network ·
grandet_resolve_modelShows one provider's price statement
Returns the raw statements a single provider has published for a model, so you can check a price or condition. Results come in pages.
Try: “Show me the evidence behind the cheapest listed price for that model.”
Network ·
grandet_quote_evidenceLists apps Grandet knows how to connect
Returns the apps Grandet has profiles for and the API protocols each supports, so a price result matches the app you will use.
Try: “Which apps does Grandet list, and which protocol does Codex use?”
Network ·
grandet_list_appsExplains relay jargon
Explains terms that relay sites use in their listings, by search word or category. It explains the words and does not check quality.
Try: “What does the term "官转" mean on relay sites?”

All six tools only read price data from grandet.ai, so nothing on your computer or accounts changes. Your questions, including model names and the app you name, go to a third-party service.

Watch out for
Server instructions tell the assistant to show site notices
At initialize, the server sends instructions that include: "Show a relevant unexpired notice briefly after the answer, at most once per notice id per conversation; respect requests to hide notices." The notice text comes from Grandet's site, so the operator can put text in your assistant's answers. Tell the assistant to hide notices, or review answers before acting on them. grandet.ai
Your questions go to a third-party service
Each call sends your search words, such as model and target app, to grandet.ai, run by the GitHub account hanzohanzhe. Do not put private project names in the prompt. grandet.ai
Prices come from relay sites, not only official vendors
Relay sites resell model access, and Grandet ranks by listed price only. Check a seller's terms before you pay. github.com
Connecting an API is not part of the server
Editing your app settings with a key is done by the separate Grandet Skill, not by the hosted MCP tools. github.com

Questions
Is the Grandet MCP server official?
Yes, in the sense that the project's own repo publishes it and it serves Grandet's own price catalogue from grandet.ai. It is not made by any model vendor or relay site whose prices it lists. It is listed in the official MCP Registry as io.github.hanzohanzhe/grandet.
Who runs the hosted server at grandet.ai?
The GitHub account hanzohanzhe, which owns the Grandet repo and lists grandet.ai as its homepage. The README names no company. Prices are read from grandet.ai, so your model and app questions go to that site.
What is the Grandet MCP server URL?
https://grandet.ai/mcp. It uses Streamable HTTP and needs no key.
Do I need an account or API key?
No. Price and free-credit lookups are anonymous.
Can it buy or connect an API for me?
No. The server only reads prices. The separate Grandet Skill can help connect an API you chose, after you sign up and create the token yourself.
Does it tell me which seller is good?
No. It ranks by listed price only. The project says prices and sellers' claims say nothing about quality.
Which AI apps work with it?
Any app that can add a remote MCP server by URL. The README documents a generic URL config and the Claude Code command; for other apps, follow that app's own steps for adding a remote server and use the install box for the config format.
Is it free?
Yes. The lookups cost nothing. Any API you then buy from a seller is paid to that seller.
Can I run it on my own machine?
Not as a documented option. The documented server is hosted at grandet.ai. The repo's own connect program can also act as a local server for connecting apps.
