# EDINET DB MCP Server

**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

| | Remote (recommended) | Local stdio server (this repo) |
|---|---|---|
| Endpoint | `https://edinetdb.jp/mcp` | runs on your machine |
| Tools | 75 | 13 core tools |
| Auth | OAuth 2.0 or API key | API key (`EDINETDB_API_KEY`) |
| Setup | add one URL | `npx`, `node`, or Docker |

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

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

### Cursor

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

### Codex CLI

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

## Quick start — local stdio server

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

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

Claude Desktop / Cursor / any stdio client:

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

From source:

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

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

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

| Environment variable | Required | Default | Purpose |
|---|---|---|---|
| `EDINETDB_API_KEY` | yes, to call tools | — | Your EDINET DB API key. Listing tools works without it. |
| `EDINETDB_BASE_URL` | no | `https://edinetdb.jp/v1` | REST API base URL. |
| `EDINETDB_TIMEOUT_MS` | no | `30000` | Per-request timeout in milliseconds. |

### 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.

| Tool | What it answers |
|---|---|
| `search_companies` | Resolve a name or securities code to an EDINET code |
| `get_company` | Full profile of one company |
| `get_financials` | Multi-year financial statement series |
| `get_segments` | Which business segment earns the money |
| `get_earnings` | Latest quarterly results and company forecast |
| `get_disclosures` | What the company filed, and when |
| `get_text_blocks` | Business overview, risk factors, MD&A as filed |
| `get_directors` | Board roster, tenure and shareholding |
| `get_shareholders` | Who holds 5%+ of this company |
| `search_shareholders` | Everything one investor holds |
| `screen_companies` | Filter the market by numeric criteria |
| `get_ranking` | Market-wide league table for one metric |
| `compare_peers` | Benchmark a company against its industry |

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.
