Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01480 | $0.01480 |
| Opus 5 | $0.00740 | $0.00740 |
| Sonnet 5 | $0.00296 | $0.00296 |
| Haiku 4.5 | $0.00148 | $0.00148 |
Grade A, and why
real-estate-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts

CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
MCP server exposing Korea's MOLIT (국토교통부) real estate transaction API to Claude Desktop. The server wraps XML endpoints from apis.data.go.kr and api.odcloud.kr, providing tools for querying apartment, officetel, villa, single-house, commercial trade/rent data, and APT subscription info.
Requires DATA_GO_KR_API_KEY from 공공데이터포털 in a .env file at the project root.
Commands
# Run all tests (requires .env with valid key, or monkeypatched key)
uv run pytest
# Run a single test file
uv run pytest tests/mcp_server/test_apartment_trades.py
# Run a single test by name
uv run pytest tests/mcp_server/test_apartment_trades.py::TestParseAptTrades::test_normal_response_returns_items
# Lint + format (auto-fix)
uv run ruff check --fix && uv run ruff format
# Type check
uv run pyright
# Security scan
uv run bandit -c pyproject.toml -r src/
# Start MCP Inspector for interactive testing
uv run mcp dev src/real_estate/mcp_server/server.py
Architecture
MCP tools are spread across modules under src/real_estate/mcp_server/:
- server.py — entry point; imports tool modules to register
@mcp.tool()decorators - __init__.py — creates the shared
mcp = FastMCP("real-estate")instance and loads.env - _helpers.py — all URL constants, shared runners, HTTP fetch, XML parse, and summary helpers
- _region.py — region code search logic
- tools/ — one file per domain:
trade.py,rent.py,subscription.py,finance.py(calculate_loan_payment,calculate_compound_growth,calculate_monthly_cashflow) - parsers/ — XML parsers:
trade.py,rent.py
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

real-estate-mcp CLAUDE.md is an instructions file published in the GitHub repository tae0y/real-estate-mcp (376 stars, last pushed 1mo ago), licensed MIT. It adds 1,480 tokens to every session, about $0.0074 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
