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 401 と WWW-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
}
