EDINET DB MCP Server

[Live] [Users] [License]

Remote MCP server for Japan's EDINET DB — structured financial data for ~3,800 Japanese listed companies, served over HTTPS with OAuth 2.0 multi-tenant authentication.

• 🌐 Endpoint: https://edinetdb.jp/mcp
• 🔐 Auth: OAuth 2.0 (or API key)
• 👥 Users: 9,000+ registered developers, analysts, and academic researchers
• 📅 Production since: 2026-03-01
• 🇯🇵 First remote MCP service for Japanese listed-company filings (by author's research as of 2026-02 month-end)

What it does

EDINET DB exposes structured financial and corporate data extracted from Japan's regulatory filings (EDINET, by the Financial Services Agency) plus public open data (gBizINFO from METI, National Tax Agency corporate registry, Wikidata). Connect from Claude Desktop, Claude Code, Cursor, Codex CLI, or any MCP-compatible client to query company financials, HR/diversity disclosures, supply chains, patents, executive profiles, and corporate history via natural language.

Two ways to connect

The remote server is the full product and needs nothing installed. The local server in this repository is a small, dependency-light stdio client over the same public REST API, for clients that cannot speak streamable HTTP or for users who would rather run the process themselves.

Quick start — remote

Claude Desktop (Custom Connector)

1. Open Claude Desktop → Settings → Custom Connectors
2. Add Connector:
   • Name: EDINET DB
   • URL: https://edinetdb.jp/mcp
   • Auth: OAuth 2.0 (discovery: https://edinetdb.jp/mcp/.well-known/oauth-authorization-server)
3. Sign in with your edinetdb.jp account (free signup at https://edinetdb.jp/signup)

Claude Code

claude mcp add edinetdb https://edinetdb.jp/mcp --transport http

Cursor

.cursor/mcp.json:

{  "mcpServers": {    "edinetdb": {      "url": "https://edinetdb.jp/mcp",      "transport": "streamable-http"    }  }}

Codex CLI

codex mcp add edinetdb https://edinetdb.jp/mcp

Quick start — local stdio server

Get a free API key at https://edinetdb.jp/developers, then:

EDINETDB_API_KEY=your-key npx -y github:edinetdb/edinet-db-mcp

Claude Desktop / Cursor / any stdio client:

{  "mcpServers": {    "edinetdb": {      "command": "npx",      "args": ["-y", "github:edinetdb/edinet-db-mcp"],      "env": { "EDINETDB_API_KEY": "your-key" }    }  }}

From source:

git clone https://github.com/edinetdb/edinet-db-mcp && cd edinet-db-mcpnpm ci && EDINETDB_API_KEY=your-key node server.js

With Docker (-i is required — the transport is stdio):

docker build -t edinet-db-mcp .docker run -i --rm -e EDINETDB_API_KEY=your-key edinet-db-mcp

Tools in the local server (13)

Each tool is a typed wrapper over one REST endpoint. The set is deliberately narrow: one tool per question a user actually asks, with no two tools covering the same ground.

For the full surface — IR documents, knowledge-graph strategies, KPI tracking, watchlists, dashboards and saved analyses — use the remote server, which exposes all 75 tools listed below.
