# Grandet MCP server

> Find the lowest listed API price for any model across official, inference and relay providers, and look up free credits.

- Connect: use the server's own URL `https://grandet.ai/mcp` (no sign-in); clients connect to it directly. The listing link is a page, not an MCP endpoint.
- Type: remote (Streamable HTTP)
- Auth: none
- Category: [AI & Machine Learning](https://mcp.tc/c/ai-ml)
- Vendor: hanzohanzhe

## About

Grandet compares listed LLM API prices per model across official APIs, inference providers and relay sites. It returns the cheapest listings with group names, units and observation dates, resolves ambiguous model names, shows the evidence behind a quote, explains relay jargon and lists free tiers and trial credits.

It runs as a hosted Streamable HTTP endpoint at https://grandet.ai/mcp. No sign-up or API key is needed. Prices are ranked by listed price only and say nothing about quality.

## What it can do

- Find the lowest listed price for a model across providers
- Compare prices within each unit (cash, USD credit, CNY credit)
- Find free API tiers, trial credits and relay free groups
- Resolve ambiguous model names to official IDs
- Inspect a provider's quote evidence for a model
- Look up relay terminology
- List application profiles for API compatibility

## Tools (6)

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport http grandet https://grandet.ai/mcp
```

2. Start Claude Code and type `/mcp`. **grandet** should show as connected.

Add `--scope user` to make it available in every project, not just this one.

### Claude Desktop

1. Open **Customize → Connectors**, click **+ Add**, then **Add custom connector**.

2. Name it **Grandet** and paste this URL:

```url
https://grandet.ai/mcp
```

3. Click **Add**. Its tools appear in the chat’s tools menu.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

### claude.ai

1. Open the connector form on claude.ai. This button fills in the name and URL for you:

[Add to claude.ai](<https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Grandet&connectorUrl=https%3A%2F%2Fgrandet.ai%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://grandet.ai/mcp` and click **Add**.

3. Turn it on in a chat from the tools menu.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**.

### ChatGPT

1. On chatgpt.com, open **Settings → Security and login** and turn on **Developer mode**.

2. Go to `chatgpt.com/plugins` and click **+** to create an app for a remote MCP server.

3. Paste `https://grandet.ai/mcp` as the server URL and choose **No authentication**.

Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts.

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=grandet&config=eyJ1cmwiOiJodHRwczovL2dyYW5kZXQuYWkvbWNwIn0%3D>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "grandet": {
      "url": "https://grandet.ai/mcp"
    }
  }
}
```

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=grandet&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fgrandet.ai%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"grandet","type":"http","url":"https://grandet.ai/mcp"}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "grandet": {
      "type": "http",
      "url": "https://grandet.ai/mcp"
    }
  }
}
```

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "grandet": {
      "serverUrl": "https://grandet.ai/mcp"
    }
  }
}
```

2. Refresh the MCP server list in Cascade.

Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers.

### Codex

```bash
codex mcp add grandet --url https://grandet.ai/mcp
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.grandet]
url = "https://grandet.ai/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http grandet https://grandet.ai/mcp
```

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file.

```json
{
  "mcpServers": {
    "grandet": {
      "type": "http",
      "url": "https://grandet.ai/mcp"
    }
  }
}
```

Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE.

Client only starts local servers? Bridge it with `npx -y mcp-remote https://grandet.ai/mcp`.
