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 volume, location scores for about 45,000 apartments nationwide, plus Reevl AI price predictions.

Free and no authentication required. Read-only.

Hosts supporting Streamable HTTP (recommended)

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

Hosts that only support stdio

Use the bridge from this repository. Nothing to install (Node 18+).

  "mcpServers": {
    "reevl": {
      "command": "npx",
      "args": ["-y", "reevl-mcp"]
    }
  }
}

The bridge does exactly one thing — it adds the MCP-Protocol-Version, Mcp-Method, and Mcp-Name headers required by the MCP 2026-07-28 specification, matching them to the body. The server rejects these values if they differ from the body (error -32020), so matching them by hand is error-prone.

Tools

All are readOnly: true, with no write, order, or brokerage features.

Don't make up units

The response always includes units. Read them as-is. If you enter a range without knowing the units, your filter will be off by a factor of 100 — for example, the jeonse-to-sale ratio is expressed as a percentage (60 means 60%), and the land per household needs to be divided by 10 to get square meters. That's why it's recommended to call describe_fields first.

Try asking it like this

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

• Find me apartments in Suwon-si under 2 billion KRW with a jeonse-to-sale ratio above 70%

• Summarize the price, jeonse-to-sale ratio, and school district score for this complex

• Summarize recent real estate policy trends using Reevl articles

Protocol

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

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

• Requests starting with initialize → that legacy revision

Supported versions can be checked at once via 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":{}}'
