カスタム コード インタープリターを使用してツールボックスを作成する

ツールボックスを作成して、カスタム コード インタープリターを追加します。 次に、ツールボックスを MCP ツールとしてエージェントにアタッチします。 詳細については、「ツールボックスとは」を参照してください。

curl -X POST "$FOUNDRY_PROJECT_ENDPOINT/toolboxes/custom-code-interpreter-toolbox/versions?api-version=v1" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $AGENT_TOKEN" \
  -d '{
    "description": "Toolbox with the custom code interpreter MCP server",
    "tools": [
      {
        "type": "mcp",
        "server_label": "custom-code-interpreter",
        "server_url": "<MCP_SERVER_URL>",
        "project_connection_id": "<MCP_PROJECT_CONNECTION_ID>",
        "require_approval": "never"
      }
    ]
  }'

ツールボックスは、 $FOUNDRY_PROJECT_ENDPOINT/toolboxes/custom-code-interpreter-toolbox/versions/<version>/mcp?api-version=v1で MCP 互換エンドポイントを公開します。ここで、 <version> は前の呼び出しによって返されたバージョンです。

ツールボックスへのリモート ツール接続を作成する

ツールボックス エンドポイントを指すリモート ツール プロジェクト接続を作成します。 呼び出し元の ID が渡されるようにユーザー Entra トークンを使用します (対象ユーザー https://ai.azure.com)。

azd ai connection create custom-code-interpreter-toolbox-conn \
  --kind remote-tool \
  --target "$FOUNDRY_PROJECT_ENDPOINT/toolboxes/custom-code-interpreter-toolbox/versions/<version>/mcp?api-version=v1" \
  --auth-type user-entra-token \
  --audience https://ai.azure.com

ツールボックスを使用するエージェントを作成する

curl -X POST "$FOUNDRY_PROJECT_ENDPOINT/agents?api-version=v1" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $AGENT_TOKEN" \

          "project_connection_id": "custom-code-interpreter-toolbox-conn"
        }
      ]
    }
  }'

応答を作成する

curl -X POST "$FOUNDRY_PROJECT_ENDPOINT/openai/v1/responses" \

  -H "Authorization: Bearer $AGENT_TOKEN" \
  -d '{
    "agent_reference": {"type": "agent_reference", "name": "CustomCodeInterpreterAgent"},
    "input": "Calculate the factorial of 10 using Python."
  }'

クリーンアップ

curl -X DELETE "$FOUNDRY_PROJECT_ENDPOINT/agents/CustomCodeInterpreterAgent?api-version=v1" \
