BOJ: Bank of Japan Statistical Data
Access Bank of Japan time-series statistics from the official flat file download service. Covers price indices (CGPI, SPPI), flow of funds, balance of payments, international investment position, BIS statistics, and TANKAN survey data.
Use Cases
- Look up Corporate Goods Price Index (CGPI/企業物価指数) trends
- Analyze Services Producer Price Index (SPPI/企業向けサービス価格指数)
- Retrieve Flow of Funds data (資金循環統計)
- Access Balance of Payments statistics (国際収支統計)
- Review BIS international statistics
- Explore TANKAN survey results (短観)

Important
- No API key required — BOJ flat files are publicly available
- Data is cached locally after first download for faster subsequent access
- Files are in Shift_JIS encoding (handled automatically)
- Data source: Bank of Japan (https://www.stat-search.boj.or.jp/)
- Python package:
pip install boj-mcporuv tool install boj-mcp
Usage Guidance
This skill appears coherent: it is a CLI client for publicly available BOJ flat files and does not request secrets. Before installing, verify the boj-mcp package source (PyPI or the uv registry), check package maintainers and release checksums, and consider installing in a sandbox or virtual environment if you have supply-chain concerns. If you need maximum assurance, review the package source code (or request a package provenance URL) prior to installation.
Capability Analysis
Type: OpenClaw Skill
Name: boj-mcp
Version: 0.1.3
The skill bundle appears benign. The `SKILL.md` provides clear, straightforward instructions for using the `boj-mcp` command-line tool to access Bank of Japan statistical data. There are no indications of prompt injection attempts against the AI agent, no suspicious commands (e.g., `curl|bash`, `eval`), no attempts at data exfiltration, persistence, or obfuscation. The installation method via `uv` for the `boj-mcp` package is standard, and the data source is explicitly stated as the official Bank of Japan website.
Capability Assessment
Purpose & Capability
Name/description, runtime commands in SKILL.md, and the required binary (boj-mcp) are consistent: the skill is a thin wrapper around a client that downloads BOJ flat files. No unrelated credentials, tools, or paths are requested.
Instruction Scope
SKILL.md instructs only to run the boj-mcp CLI to list/search/download BOJ datasets and to test connectivity. It notes local caching and character encoding handling — both reasonable for this use case. The instructions do not ask the agent to read unrelated files, secrets, or to transmit data to third-party endpoints.
Install Mechanism
Install spec uses a third-party package installer ('uv' package kind) that will create a binary named boj-mcp; SKILL.md also suggests 'pip install boj-mcp' as an alternative. Installing third-party packages executes external code, which is expected for a CLI client but carries normal supply-chain risk. Verify package provenance (registry, checksums) before installing.
Credentials
No environment variables, credentials, or config paths are required. The skill does local caching but does not request secrets or access to unrelated services — this is proportionate to its stated purpose.
Persistence & Privilege
always is false and the skill does not request any elevated or persistent platform-wide privileges. Local caching is normal for a data client and the skill does not attempt to modify other skills or system-wide agent configs.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install boj-mcp - After installation, invoke the skill by name or use
/boj-mcp - Provide required inputs per the skill's parameter spec and get structured output
