Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00552 | $0.00552 |
| Opus 5.5 | $0.00221 | $0.00221 |
| Sonnet 5.5 | $0.00110 | $0.00110 |
| Haiku 4.5 | $0.00055 | $0.00055 |
Grade A, and why
basercms-mcp copilot-instructions.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

MCPの実装について
- MCPの実装には、basercms-js-sdk を使用します。
- MCPサーバーのライブラリには、
modelcontextprotocol/sdkを利用します。 - MCPサーバーとして利用できる機能は、
src/tools/に配置します。 - baserCMSのエンティティを操作する機能は、baserCMSのプラグインごとにフォルダで分類し（bc-blog等）、エンティティごとに複数形でファイルを作成します（blog-posts.ts）、
機能の命名規則
- 単一取得：get{EntityName}
- 複数取得：get{EntityNames}
- 作成：add{EntityName}
- 更新：edit{EntityName}
- 削除：delete{EntityName}
動作確認
- MCPサーバーの動作確認は、
src/index.tsを実行することで行います。その際、.env を読み込む仕様になっています。 - 各機能の動作確認は、
src/index.tsに、MCPサーバーのパラメーターを標準入力より渡すか、request.jsonにMCPサーバーのパラメーターを記述した上で、src/index.tsに引数として渡すことで行います。 - 動作確認の際は、
ts-nodeを利用する前提とします。 - 新しいメソッドを実装したら、そのまま、動作確認を行います。その際、新しくファイルを作らず直接実行しないでください。
- やむを得ず、新しくファイルを作成する必要があった場合には、実行後に削除してください。
- 結果の確認は最後のターミナルコマンドから取得します。
- 動作確認のコマンド実行に限り、承認を得ず実行することができます。
注意事項
ファイルアップロードについて
ファイルアップロードの際は、Node.js の場合、fs を利用してアップロードします。
import fs from 'fs';
const value = fs.createReadStream('./asset_sample/test.jpg');
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
