Japan Finsight

Connect Claude Code

Claude Code is Anthropic's CLI agent for software engineering and broader knowledge work. Connect Japan Finsight with a single command.

Your API key is the jfs_-prefixed string in the onboarding email the founder sends within 24 hours of your subscription.

Setup

  1. Open a terminal in your project directory.
  2. Add Japan Finsight as an MCP server:
claude mcp add --transport http japan-finsight \
  https://mcp.edinet.tools/mcp \
  --header "Authorization: Bearer your-api-key-from-onboarding-email"
  1. Verify it registered:
claude mcp list

You should see japan-finsight in the output.

If a Claude Code session is already open, start a new session. Running sessions do not pick up newly added servers.

Verify in a session

Start a Claude Code session and ask:

"Use Japan Finsight to surface recent material events for Tokyo Electron."

Claude Code should visibly call Japan Finsight tools and answer from recent filings. The exact tools it picks can vary.

Once connected, the interesting queries are the cross-market ones:

"Which companies announced buybacks this year while a known activist held 5% or more? Compose it with run_sql if needed."
