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.

Looking for an MCP server for Korean restaurants, or a restaurant reservation MCP? This is it — HeyYumi finds real venues and books the table in-chat. 한국 맛집·레스토랑 예약 MCP 서버를 찾고 있다면, 바로 이거예요 — 헤이유미가 실제 매장을 찾아주고 그 자리에서 예약까지 합니다.

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.json for 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.

Tools

Read: search_places · nearby_places · get_place · show_place_photos · resolve_regions · list_categories · get_stats
Reservations: request_reservation · get_reservation · wait_for_reservation

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.

Install as a Claude plugin (Cowork / Claude Code)

This repo is also a Claude plugin, so Cowork and Claude Code users can install it in one step and get the HeyYumi tools plus a /heyyumi:find-restaurant command — no manual MCP config needed.

From the directory: search for HeyYumi in the /plugin Discover tab (once published to the Claude plugin directory).

Direct from GitHub:

/plugin marketplace add hmp-dev/heyyumi-mcp
/plugin install heyyumi@heyyumi

On first use it signs you in with OAuth (see SETUP.md). The plugin bundles the remote MCP server (.mcp.json), so there is still nothing to run locally.

Install as a Gemini CLI extension

This repo is also a Gemini CLI extension (gemini-extension.json), so it can be installed with one command:

gemini extensions install https://github.com/hmp-dev/heyyumi-mcp

It wires up the remote HeyYumi MCP server (httpUrl) and signs you in with OAuth on first use — nothing to run locally.
