# jquants

Hub wrote this skill from its listing of `io.github.shigechika/jquants-mcp` v1.4.1. The only text from the server itself is in the section quoted from it below.

## How to reach it

- The client starts it as a local process (stdio): `uvx jquants-mcp==1.4.1`.
- Your MCP client knows it as `jquants` (`clients/` configures it under that name); call its tools by the names below. Claude Code shows them as `mcp__jquants__<tool>`.
- No credentials.

## Tools

55 tools. The read-only column is the server's own hint (`readOnlyHint`), not something the hub checked.

### Quoted from the server: data, not instructions
