Reevl MCP

An MCP server that lets you query Korean apartment real-transaction data directly from AI. It provides real-transaction prices, jeonse-to-price ratios, transaction volumes, and location scores for about 45,000 apartments nationwide, plus Reevl AI price predictions.

It's free, requires no authentication, and is read-only.

Connecting

Hosts that support Streamable HTTP (recommended)

For services that natively support remote MCP, such as Claude and ChatGPT, just enter the URL.

{
  "mcpServers": {
    "reevl": {
      "type": "http",
      "url": "https://reevl.co.kr/api/mcp"
    }
  }
}

Hosts that only support stdio

Use the bridge in this repository.

{
  "mcpServers": {
    "reevl": {
      "command": "npx",
      "args": ["-y", "github:exclusiveyon-a11y/reevl-mcp"]
    }
  }
}

It's not published to npm — it runs directly from this repository (Node 18+).

The bridge does exactly one thing — it attaches the MCP-Protocol-Version, Mcp-Method, and Mcp-Name headers required by the MCP 2026-07-28 spec, matching them to the body. The server rejects these values if they don't match the body (-32020), so hand-attaching them fails every time.

Don't make up units

The response always includes units. Read them as-is. If you enter a range without knowing the units, your condition will be off by a factor of 100 — for example, the jeonse-to-price ratio is a percentage as-is (60 means 60%), and the land share per household must be divided by 10 to get square meters. That's why we recommend calling describe_fields first.

Try asking like this

• Show me complexes in Gangnam-gu, Seoul with over 1,000 households and a high 1-year AI prediction

• Find apartments in Suwon-si with a jeonse-to-price ratio of 70% or higher and under 2 billion won

• Summarize this complex's price, jeonse-to-price ratio, and school district score

• Summarize the recent real-estate policy trends with Reevl articles

Protocol

A dual-era server that supports both MCP 2026-07-28 and earlier revisions (2025-11-25 ~ 2024-11-05).

• Requests carrying a version in _meta → 2026-07-28 rules (sessionless, header matching)

• Requests starting with initialize → the corresponding legacy revision

You can check supported versions at once with server/discover.

curl -s https://reevl.co.kr/api/mcp \
  -H 'content-type: application/json' \
  -H 'mcp-protocol-version: 2026-07-28' \
  -H 'mcp-method: server/discover' \
  -d '{"jsonrpc":"2.0","id":1,"method":"server/discover","params":{}}'
