Jquants Mcp
PassAudited by ClawScan on May 1, 2026.
Overview
This appears to be a read-only J-Quants market-data skill, but users should notice that it installs an external Python tool and requires J-Quants login credentials.
This skill looks coherent and read-only for accessing J-Quants market data. Before installing, confirm you trust the jquants-mcp package source and provide only the J-Quants credentials needed for this API.
Findings (2)
Artifact-based informational review of SKILL.md, metadata, install specs, static scan signals, and capability signals. ClawScan does not execute the skill or run runtime probes.
The installed tool may authenticate to J-Quants using your account credentials to retrieve market data.
The skill asks for J-Quants account credentials. That matches the stated API-access purpose, but users should recognize they are granting account-authenticated access.
Requires `JQUANTS_MAIL_ADDRESS` and `JQUANTS_PASSWORD` environment variables
Use a dedicated J-Quants account if possible, store credentials as environment variables only, and avoid sharing logs or outputs that may expose account details.
Installing the skill will install and run code from the named package source, so package provenance matters.
The skill depends on an external package-installed binary. This is normal for a CLI/MCP integration, but the provided artifacts do not include package source details beyond the package name.
