HeyYumi MCP
Ground your AI in verified Korean venue data: search, filter and book real restaurants, cafes and bars across Seoul, Gyeonggi, Busan and Jeju — with in-chat reservations at partner venues.
This is a remote, hosted MCP server. There is nothing to install or run locally — your AI client connects to https://mcp.heyyumi.ai/mcp over Streamable HTTP and signs in with OAuth (or an API key).
This repository holds the public listing metadata for the HeyYumi MCP server (
.mcp.jsonfor directory auto-detection). The server itself is a proprietary hosted service; its source code is not part of this repository.
What it does
Instead of hallucinating restaurants, your agent calls tools to work with real, cross-verified venues:
- Search & filter by neighborhood/station/landmark, cuisine, price, atmosphere, and 40+ attributes (wifi, parking, group-friendly, private room, vegan options, English-speaking staff, open-now, and more).
- Find nearby venues by coordinates.
- Read honestly — confidence scores, freshness, closure risk, and reputation basis so answers stay grounded, not guessed.
- Reserve in-chat — at Yumi Partner venues, request and confirm a real table reservation without leaving the conversation.
Data is reconciled and confidence-scored across sources, so agents reach the right answer in fewer calls. The same data is available over MCP and REST, with OAuth sign-in for Claude and ChatGPT or an API key for other clients.

Connect
Add this to your client's MCP config (e.g. ~/.cursor/mcp.json):
{
"mcpServers": {
"heyyumi": {
"url": "https://mcp.heyyumi.ai/mcp"
}
}
}
Your client will prompt you to sign in (OAuth). Then try prompts like:
Find a quiet cafe near Hongdae with wifi and power outlets for working.Recommend a Korean BBQ place in Gangnam that takes reservations, and book a table for 4 tonight.I'm near Aewol in Jeju — show highly rated seafood restaurants that are open now.
