Quick Start / クイックスタート

Use the remote endpoint from any Streamable HTTP compatible MCP client:

https://mcp.bid-jp.com/mcp

The remote endpoint requires OAuth 2.0. A request without Authorization receives 401 with WWW-Authenticate: Bearer resource_metadata="https://mcp.bid-jp.com/.well-known/oauth-protected-resource/mcp". Claude.ai, ChatGPT, and MCP Inspector run the flow for you (Dynamic Client Registration + PKCE S256), so you only click approve. Plain curl will not work without a token — use local stdio below to try it without authentication.

リモートエンドポイントは OAuth 2.0 必須です。Authorization なしのリクエストは 401WWW-Authenticate ヘッダーを返します。Claude.ai / ChatGPT / MCP Inspector は認可フローを自動で処理するため、承認ボタンを押すだけです。認証なしで試したい場合は下記のローカル stdio を使ってください。

Endpoint jarak jauh memerlukan OAuth 2.0. Permintaan tanpa Authorization mendapat 401 beserta header WWW-Authenticate. Klien seperti Claude.ai, ChatGPT, dan MCP Inspector menjalankan alur otorisasi secara otomatis. Untuk mencoba tanpa autentikasi, gunakan stdio lokal di bawah.

With MCP Inspector:

npx --yes @modelcontextprotocol/inspector

Set Transport Type to Streamable HTTP and use the remote URL above. Do not use the default STDIO sample command such as mcp-server-everything.

Sample search_bids arguments:

{
  "query": "システム",
  "prefecture": "鹿児島県",
  "category": "役務",
  "limit": 3
}

Local stdio (no authentication required):

npx --yes jp-bids-mcp

CSV export:

npx --yes jp-bids-export --prefecture 鹿児島県 --category 役務 --query システム --days 7 > bids.csv

Check without starting an MCP session:

npx --yes jp-bids-mcp --version

Interoperability / 相互運用 / Interoperabilitas

JP Bids MCP pairs with the J-Grants MCP (Digital Agency of Japan) to cover both government contracts and grants in a single conversation.

# Search bids (JP Bids MCP) and grants (J-Grants MCP) simultaneously
"鹿児島県のITシステム調達案件と、中小企業向けDX補助金を同時に探してください。"

See examples/jgrants-integration/ for ready-to-use Claude Desktop and Cursor configuration files, and three end-to-end workflow examples.
Technical integration details: docs/integrations/jgrants.md.

JP Bids MCP also pairs with freee MCP (freee K.K.) for procurement-to-accounting automation — financial readiness checks, post-award deal entries, and invoice generation from bid data. See examples/freee-integration/.

JP Bids MCP, J-Grants MCP, and freee MCP are independent servers operated by separate organizations. Results are reference information; always verify against official documents.

Notes / 注意事項
