Quick Start

python -m venv .venv
.venv\Scripts\activate
pip install -r requirements.txt
copy .env.example .env
python server.py

The server starts on 127.0.0.1:8765 and exposes the MCP endpoint at /mcp.

Environment Variables

DATA_GO_KR_API_KEY=
VWORLD_API_KEY=

• DATA_GO_KR_API_KEY: public data portal API key used for benchmark probing and future official integrations
• VWORLD_API_KEY: VWorld API key used for address-to-PNU lookup and cadastral queries

ChatGPT Developer Mode

ChatGPT cannot connect to localhost directly. Expose the server with ngrok http 8765 or Cloudflare Tunnel, then use the generated HTTPS URL in ChatGPT Settings -> Connectors -> Create.

Project Domains

Every tool expects a domain parameter.

• 건축
• 토목_도로
• 토목_상하수도
• 토목_하천
• 조경
• 복합

Landscape-specific legal and procedure data is not fully implemented yet. The server returns a readiness message instead of pretending the data is complete.

Data Notes

• civilplan_mcp/data/land_prices/ is intentionally empty in git.
• Put downloaded land-price CSV, TSV, or ZIP bundles there for local parcel-price lookup.
• The loader supports UTF-8, CP949, and EUC-KR encoded tabular files.

Update Automation

The updater package includes scheduled jobs for:

• January 2, 09:00: wage H1 + waste + indirect rates H1
• July 10, 09:00: standard market price H2 + indirect rates H2
• September 2, 09:00: wage H2

If parsing fails, the server creates .update_required_* flag files and emits startup warnings.

Known Limitations

• Official land-use planning data still depends on unstable external services. The server tries official and HTML fallback paths, but some parcels may still return partial zoning details.
• Land-price lookup requires manually downloaded source files under civilplan_mcp/data/land_prices/.
• Nara benchmark validation currently probes API availability and falls back to local heuristics when the public endpoint is unavailable.
• Updater fetchers are conservative and may request manual review when source pages change.

Verification

Current local verification command:

pytest tests -q
