Overview

AI-generated overview

A hosted MCP server that lets an assistant look up Japanese EDINET (FSA) filings for a company or filer, plus related filings, large shareholding and tender-off

What you can do
List the server's tools with prices, data sources, licensing, daily limits and data freshness via the catalog tool. Look up what a Japanese company or other filer submitted to EDINET in the last 365 days, with document ID, type, submission time, period, filer and issuer. Trace how a filing relates to others: parent and child documents, filer, large shareholding issuer, tender offer subject and listed subsidiaries. Find large shareholding and tender offer filings naming a given Japanese issuer, newest first. Re-fetch the stored result of a settled paid call by receipt ID.
When to use it
Useful when you need factual, source-based answers about recent Japanese regulatory filings, such as checking a company's EDINET submissions, tracing amendments and related documents, or finding large shareholding and tender offer filings for an issuer.
Requirements
Runs as a hosted remote endpoint over streamable HTTP; no local package, account, API key or environment variable is declared. Network access to the endpoint is needed. Some calls are paid, and the catalog tool lists prices and daily limits.
Before you install
Some tools are paid calls; check prices and daily limits with the catalog tool before use. Paid results are stored and can be re-fetched by receipt ID for 90 days after settlement; unknown or unsettled receipt IDs return RECEIPT_NOT_FOUND. Data comes from the service's own EDINET index and is described as facts only.

Installation

In SourceWeft

  1. Open Japan EDINET Filing Index in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.mk-career-planning%2Fjp-edinet/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
